Menlo Park, California
Menlo Park is a city in San Mateo County, California, located on the San Francisco Peninsula in the Silicon Valley region of the San Francisco Bay Area. Incorporated on November 23, 1927, the city had an estimated population of 33,040 residents as of July 1, 2024.[1] Known worldwide as the "Capital of Venture Capital," Menlo Park serves as a central hub for high-technology innovation and investment, hosting the global headquarters of Meta Platforms, the Stanford Research Institute (SRI)—where technologies including packet switching and Siri were developed—and numerous prominent venture capital firms such as Andreessen Horowitz and Kleiner Perkins.[2][3] The city's economy is dominated by the technology sector, contributing to its affluent character and proximity to Stanford University, which has fostered a ecosystem of startups and research-driven enterprises.[4] Menlo Park also features the oldest continuously operating railroad passenger station in California, designated as a state landmark, underscoring its historical ties to regional transportation development.[5]Name
Etymology and historical significance
In 1854, Irish immigrants Dennis J. Oliver and D.C. McGlynn, brothers-in-law from County Galway, purchased approximately 1,700 acres of land in the area as part of the former Rancho de las Pulgas, naming their estate Menlo Park in homage to their ancestral village of Menlough (also spelled Menlo), which derives from the Irish Mianloch meaning "little lake."[6][7] The settlers erected a prominent wooden gate along what is now El Camino Real to mark the entrance to their property, featuring a central arch inscribed with "Menlo Park" and the date "August 1854," flanked by smaller arches bearing their surnames; this structure served as a formal boundary and early identifier for the ranch.[6][8] The gate symbolized the Irish heritage of the founders and became a focal point for local identity, enduring until its destruction by a vehicle in 1922, after which it persisted in cultural memory as a landmark evoking the area's agrarian and immigrant origins.[6] In 1863, as the San Francisco and San Jose Railroad extended service to the region—with the inaugural run on October 23—a station official, observing the nearby gate, adopted "Menlo Park" as the designation for the stop, which lacked a prior name and marked the line's endpoint at the time.[6][9] This railroad naming cemented the moniker for the surrounding community, facilitating its transition from isolated ranchland to a recognized suburban node and underscoring the gate's role in shaping regional nomenclature and early development patterns.[10] A full-scale replica of the gate, dedicated on March 17, 2019, now stands near the Menlo Park Library, reinforcing its enduring emblematic value in preserving historical continuity amid modern growth.[11]History
Early settlement and railroad development
In 1851, following California's admission to the Union, Irish immigrants Dennis J. Oliver and Daniel C. McGlynn, brothers-in-law, purchased 659 acres from the former Rancho de las Pulgas land grant to establish a ranch in the area.[12] Three years later, in 1854, they named the property Menlo Park—after their ancestral estate in County Galway, Ireland—and erected wooden gates inscribed with the name along the County Road (present-day El Camino Real), signaling the onset of formalized settlement.[12] [9] These early efforts centered on agricultural and ranching activities, capitalizing on the fertile soils near San Francisquito Creek to support farming communities that subdivided larger tracts into productive lands.[12] The completion of the San Francisco and San Jose Railroad to San Francisquito Creek in 1863 marked a pivotal shift, with the line's inaugural service reaching the Menlo Park station stop on October 18 of that year.[6] [12] Concurrently, local landowners laid out the Menlo Park Villa subdivision, positioning the site as a convenient rail halt for passengers traveling southward from San Francisco.[10] The station's wooden structure was upgraded and formalized in 1867, enhancing connectivity and drawing an influx of settlers interested in both continued agriculture and nascent suburban living.[12] This rail infrastructure catalyzed demographic expansion, enabling San Francisco commuters to establish farms and residences amid the Peninsula's mild climate, with the population rising from approximately 250 residents in 1884 to 400 by 1890.[10] By the late 19th century, Menlo Park had evolved from isolated ranchlands into a hybrid agrarian-suburban enclave, its growth tethered to the railroad's role in integrating the area into broader regional commerce and transport networks.[10]World War I era and Camp Fremont
In July 1917, following the United States' entry into World War I, the U.S. Army selected a site in Menlo Park for Camp Fremont, leasing approximately 23,000 acres of land, including portions from Stanford University and local landowners, to establish a major training facility for the 8th Infantry Division.[13][14] Construction began rapidly that month, transforming agricultural and sparsely developed areas into a cantonment with barracks, training fields, and mock trench systems in the nearby foothills, designed to simulate European battlefield conditions.[15][16] The camp's headquarters were situated in the village of Menlo Park, effectively integrating military operations with the downtown area and accelerating the conversion of local infrastructure for wartime needs.[13] By early 1918, Camp Fremont housed over 8,000 troops, surpassing the local civilian population and causing immediate strains on Menlo Park's limited resources, including water, sanitation, and housing for accompanying families and merchants.[17] At its peak, the facility accommodated nearly 27,000 personnel, with a total of about 43,000 soldiers rotating through for training in infantry tactics, rifle marksmanship, and field maneuvers before potential deployment.[18] This influx spurred temporary economic activity, as local businesses expanded to serve soldiers, but also overwhelmed existing utilities, prompting federal investments in infrastructure such as a main sewer line connecting Menlo Park to Atherton to handle camp waste and prevent health risks.[19] The camp operated until the Armistice in November 1918, with full closure ordered in September 1919 amid demobilization, after which surplus buildings were auctioned and the site repurposed, including portions converted into Fremont Memorial Park.[15][20] While few Camp Fremont trainees saw combat on the Western Front due to the war's end, the facility's presence left a lasting imprint on land use, with remnants of training earthworks persisting and federal infrastructure upgrades facilitating Menlo Park's transition toward permanent urbanization; however, significant veteran resettlement in the immediate area was limited, as most soldiers dispersed post-discharge without forming concentrated communities locally.[20][16][21]Post-war growth and institutional foundations
Menlo Park's incorporation as a city on July 16, 1927, marked the beginning of organized suburban development, shifting the community from its rural agricultural roots toward structured residential expansion. The initial city limits encompassed 1.2 square miles with a population of approximately 2,200 residents as recorded in the 1930 census.[22] During the 1920s and 1930s, improvements in transportation infrastructure, including road expansions and rail connectivity, supported modest population growth to 3,200 by 1940, fostering the emergence of new neighborhoods amid the broader regional shift from farming to suburban living.[21][22] The post-World War II era accelerated this trajectory with rapid suburbanization, as returning veterans and economic prosperity drove demand for housing; the population surged to 13,587 by the 1950 census, quadrupling from 1940 levels.[23] New residential subdivisions proliferated, supported by federal programs like the GI Bill and local zoning that prioritized single-family homes, doubling the city's area to 2.1 square miles by 1948.[22] In neighborhoods such as Sharon Heights, development gained momentum in the 1950s, transitioning former estates into modern housing tracts with few pre-1950 dwellings giving way to broader real estate activity that emphasized spacious lots and proximity to emerging amenities.[24] A pivotal cultural institution emerged in 1951 with the establishment of Sunset magazine's headquarters at 80 Willow Road, a seven-acre campus designed in the California Ranch style to embody the publication's vision of Western living.[25] The site featured demonstration gardens, test kitchens, and editorial facilities that promoted practical ideals of home design, outdoor recreation, and regional self-sufficiency, influencing architectural trends and lifestyle norms across the West for decades.[26] This development reinforced Menlo Park's role as a hub for aspirational suburban culture, distinct from purely economic drivers, by integrating media-driven innovation with community foundations.[25]Mid-20th century innovations and SRI International
The Stanford Research Institute was founded on November 13, 1946, by Stanford University trustees as an independent nonprofit organization headquartered in Menlo Park, California, to conduct applied research supporting postwar economic development in the region.[27] Initially funded through contracts with government agencies and private industry, it focused on fields such as electronics, mechanical engineering, and chemistry, employing over 100 staff by 1948 and expanding facilities in Menlo Park to accommodate growing R&D demands.[28] This establishment marked the onset of organized technological innovation in Menlo Park, transitioning the area from agricultural and residential roots toward a research-oriented economy. SRI's mid-century advancements included pioneering work in computing and networking that presaged the digital age. In 1964, engineer Douglas Engelbart and colleagues at SRI invented the computer mouse—a wooden prototype with wheels for tracking—and developed early concepts for graphical user interfaces.[29] This culminated in Engelbart's 1968 "Mother of All Demos," a public demonstration of hypertext, video conferencing, and collaborative editing systems, which influenced subsequent personal computing paradigms.[30] Concurrently, SRI contributed to ARPANET precursors by hosting the Network Information Center and one of the initial four nodes; the first successful packet-switched transmission occurred on October 29, 1969, linking UCLA to SRI's Interface Message Processor.[31] These efforts positioned SRI as a nexus for knowledge spillovers in Silicon Valley, where proximity to academic and industrial partners accelerated technology transfer to private enterprise. By the 1970s, SRI's research in packet switching and human-computer interfaces had informed protocols adopted by emerging firms, demonstrating how concentrated R&D clusters generate causal chains of innovation through talent aggregation and iterative experimentation.[32] The institute's independence from Stanford in 1970 further enabled flexible contracting, yielding over 100 patents by decade's end and underscoring Menlo Park's role in fostering scalable tech ecosystems without relying on narrative-driven interpretations of progress.[27]Late 20th to early 21st century tech expansion
During the 1980s and 1990s, Menlo Park emerged as a central node in Silicon Valley's venture capital ecosystem, with Sand Hill Road concentrating dozens of firms that channeled investments into startups leveraging innovations from adjacent Stanford University.[33] Firms such as Kleiner Perkins, founded in 1972 but expanding amid the personal computing and internet surges, and Sequoia Capital provided critical funding for hardware-to-software transitions, with collective investments reaching hundreds of billions by the early 2000s to fuel scalable tech enterprises.[34][33] This clustering, proximate to Stanford's research output, created a feedback loop where academic talent and prototypes attracted risk capital, driving firm formations in software, networking, and biotech sectors.[35] The period saw the maturation of corporate campuses tailored to tech operations, exemplified by Sun Microsystems' expansive facilities in Menlo Park, which supported its growth from a 1982 founding to a major player in workstations and servers by the 1990s.[36] In 2011, Facebook announced its relocation from Palo Alto to this former Sun campus at 1601 Willow Road, securing a 15-year lease on the 1-million-square-foot site with an option to purchase, to house its expanding workforce amid surging user growth.[36][37] The move, completed by late 2011, underscored Menlo Park's appeal for large-scale tech infrastructure, where land availability and infrastructure supported rapid scaling without the denser constraints of neighboring Palo Alto.[38] These developments amplified economic effects through high-wage employment and multiplier spending, with tech occupancy boosting local commercial real estate values and tax revenues, though reliant on a regulatory framework favoring innovation over stringent zoning or labor mandates prevalent elsewhere.[39] Venture-backed exits and IPOs from Sand Hill-funded companies further entrenched Menlo Park's role, sustaining a cycle of reinvestment that differentiated it from earlier manufacturing-focused phases of Silicon Valley growth.[33]Recent developments since 2010
Meta Platforms, Inc. (formerly Facebook), headquartered in Menlo Park since consolidating its campus there in 2011, undertook significant expansions in the 2010s and 2020s, including a 2020 redevelopment of the former TE Connectivity site that added approximately 962,400 square feet of office space.[40] These developments supported a substantial local workforce concentration, though exact Menlo Park-specific employee counts are not publicly detailed; globally, Meta employed 67,317 people as of late 2023, with the campus serving as a primary hub amid ongoing infrastructure strains from traffic and utilities.[41] By 2024, the company subleased portions of its expanded facilities while conducting workforce reductions, reflecting broader tech sector adjustments.[42] Menlo Park's population, which grew modestly from about 32,000 in 2010 to a peak near 35,000 in the mid-2010s, began declining post-2020, reaching an estimated 32,775 in 2023—a 1.65% drop from the prior year—amid Bay Area-wide trends of remote work enabling out-migration during and after the COVID-19 pandemic.[43] Regional data indicate a net loss of over 100,000 residents across the San Francisco Bay Area from 2020 to 2025, or roughly 1% of the total, as high living costs and flexible employment prompted relocations.[44] These shifts contributed to fluctuating local demographics, with median household income rising to over $200,000 by 2023 despite the population dip.[43] Housing supply constraints intensified in the 2010s and 2020s due to restrictive zoning and soaring costs, prompting state-mandated reforms; California assigned Menlo Park a regional housing needs allocation of about 3,000 units for 2023–2031 across income levels, leading to zoning updates allowing up to 100 units per acre in downtown areas by late 2023.[45][46] Building permits surged to 176 new dwelling units in 2024 from 65 the previous year, including plans to convert downtown parking lots into at least 345 affordable units, though proposals faced resident pushback over density and parking loss.[47][48] Empirical evidence from inclusionary requirements—mandating 15% below-market-rate units in large projects—highlights efforts to mitigate affordability gaps, where median home prices exceed $2 million, constraining supply amid tech-driven demand.[49]Geography
Location, topography, and climate
Menlo Park is situated in San Mateo County within the San Francisco Bay Area of California, at the eastern edge of the county adjacent to San Francisco Bay.[50] The city lies approximately 27 miles southeast of downtown San Francisco, with geographic coordinates of 37°27′ N latitude and 122°11′ W longitude.[51] It borders Palo Alto to the south, Atherton to the west, Redwood City to the north, and East Palo Alto to the northeast, encompassing an area influenced by the bay's proximity.[52] The topography of Menlo Park features flat alluvial plains typical of the bay shoreline, with minimal elevation variation. According to USGS data, the approximate elevation is 72 feet (22 meters) above sea level.[53] This low-lying terrain, shaped by sedimentary deposits from the bay and nearby streams, exposes the area to flood risks during periods of high tidal surges or heavy winter rains, exacerbated by its position near Dumbarton Bay.[53] Menlo Park has a warm-summer Mediterranean climate (Köppen Csb), marked by mild, wet winters and warm, dry summers moderated by coastal fog and bay breezes. Annual precipitation averages about 14 inches (354 mm), concentrated from November to March, while summers receive negligible rainfall. Average high temperatures reach 77°F (25°C) in August, with lows around 59°F (15°C); winter highs average 59°F (15°C) in January, with lows near 41°F (5°C).[54][55][56]Environmental and land use features
Menlo Park spans approximately 9.8 square miles of land area, bordered by San Francisco Bay to the east, where managed wetlands and tidal marshes constitute key environmental features.[57] The city's eastern edge includes the Bedwell Bayfront Park, a 160-acre open space with restored habitats supporting endangered species such as the salt marsh harvest mouse (Reithrodontomys raviventris) and Ridgway's rail (Rallus obsoletus), which rely on pickleweed-dominated salt marshes for foraging and nesting.[58][59] These baylands, part of broader regional ecosystems, also host migratory birds and provide buffers against sea-level rise through natural sediment accretion, with restoration efforts enhancing transition zones between uplands and tidal areas.[60] Land use patterns emphasize low-density residential development, with single-family zoning (R-1 districts) dominating over 70% of residential parcels, enforcing minimum lot sizes of 4,900 square feet per dwelling unit to maintain suburban character.[61] This configuration yields a population density of about 3,360 persons per square mile as of the 2020 census, lower than neighboring urban centers, which preserves private green spaces in yards and setbacks amid expanding commercial tech campuses to the west.[62] The Open Space and Conservation (OSC) district further designates lands for passive recreation and habitat protection, limiting intense development to safeguard scenic ridges and creek corridors like Los Trancos Creek.[63] Tensions between conservation and development arise from tech-driven growth pressures, where low-density zoning has empirically sustained higher per-acre green coverage—estimated at 20-25% vegetative land in residential zones—compared to higher-density alternatives, though bayfront encroachments risk habitat fragmentation without adaptive measures like the SAFER Bay Project's hybrid levee-marsh designs.[64][59] High property values, exceeding $3 million median for single-family homes in 2023, incentivize preservation of these features, as owners leverage tax benefits under California's Williamson Act for agricultural and open space easements on peripheral lands.[65]Demographics
Population trends and census data
The population of Menlo Park exhibited modest growth in the early 20th century, reaching 2,254 by the 1930 census, before accelerating rapidly after World War II due to suburban expansion.[23] From 3,258 in 1940, the figure surged to 13,587 by 1950, reflecting broader regional development patterns.[23] Subsequent decades showed steadier increases, with the population stabilizing around 26,000-28,000 from 1960 to 1990 before rising again to 30,785 in 2000 and 32,026 in 2010, driven by proximity to emerging tech hubs.[23]| Year | Population |

Ethnic composition and socioeconomic indicators
According to the 2020 United States Census, Menlo Park's population exhibited a racial and ethnic composition of 57.5% White alone, 17.7% Asian alone, 3.5% Black or African American alone, 0.6% American Indian and Alaska Native alone, 0.2% Native Hawaiian and Other Pacific Islander alone, and 10.4% two or more races; separately, 16.0% of residents identified as Hispanic or Latino of any race. Among non-Hispanic residents, Whites comprised approximately 52.4% and Asians 18.2%, reflecting significant immigration from Asia driven by employment in the local technology sector.[43]| Racial/Ethnic Group | Percentage (2020 Census) |
|---|---|
| White alone (total) | 57.5% |
| Asian alone | 17.7% |
| Hispanic or Latino (any race) | 16.0% |
| Black or African American alone | 3.5% |
| Two or more races | 10.4% |
Government and Politics
Local governance structure
Menlo Park employs a council-manager form of government, with the council serving as the legislative and policy-making body and the appointed city manager handling administrative operations. Incorporated on November 23, 1927, the city adopted this structure in 1952 to centralize executive functions under professional management.[1][74] The city manager, reporting to the council, oversees departments including public works, community development, and finance, ensuring implementation of council directives while maintaining operational efficiency.[75] The five-member city council is elected to four-year staggered terms from single-member districts, a system implemented in 2018 following legal assessments under the California Voting Rights Act to enhance representational equity over prior at-large elections.[1][76] Council meetings occur biweekly on the second and fourth Tuesdays, focusing on ordinance adoption, budget approval, and strategic planning. The mayor, selected annually by the council from its members, presides over meetings and represents the city ceremonially but holds no veto power.[77] Annual budgets prioritize public safety and infrastructure, as evidenced by fiscal year 2024–25 allocations from $73.4 million in general fund revenues, which fund police and fire services alongside maintenance of streets, parks, and facilities to sustain the city's operational framework.[78] This approach reflects prudent resource management, with conservative revenue projections and targeted expenditures to address core municipal needs amid economic variability.[79]Elected officials and political leanings
Menlo Park operates under a council-manager form of government where the five-member city council selects the mayor annually from among its members. As of January 2025, the mayor is Drew Combs, representing District 2, who was unanimously selected on December 12, 2024, for a one-year term.[80] The vice mayor is Betsy Nash. The other council members include Cecilia Taylor (District 1), Jeff Schmidt (District 3), and Jennifer Wise (District 5), with districts established in 2018 to enhance representation.[77] [81] At the state level, Menlo Park falls within California's 23rd Assembly District, represented by Democrat Marc Berman since 2016, and the 13th Senate District, represented by Democrat Josh Becker since 2020.[82] [83] Federally, the city is part of the 16th Congressional District, represented by Democrat Sam Liccardo, who won the seat in the November 2024 election following Anna Eshoo's retirement.[84] Historically, the mayoral position has rotated among council members, with notable figures including Billy Ray White, the first African-American mayor serving in the 1970s, and Peg Gunn, who held the role multiple times in the 1980s. [85] Recent mayors such as Cecilia Taylor (2024) and Ray Mueller reflect the non-partisan local elections, though council members often align with broader progressive priorities evident in regional politics.[77] Menlo Park's electorate demonstrates strong Democratic leanings, consistent with San Mateo County's voter patterns. In the 2020 presidential election, San Mateo County supported Joe Biden with 73.8% of the vote against Donald Trump's 24.5%, with Menlo Park precincts typically exceeding 80% for Democratic candidates due to its affluent, tech-oriented demographics.[86] Voter registration in the county shows Democrats comprising about 50% of registered voters, far outpacing Republicans at around 15%, fostering one-party dominance in local and higher-level representation that may constrain policy diversity despite the city's innovation-driven economy.[87] High voter turnout, often above 80% in general elections, underscores engaged participation but reinforces liberal majorities across ballots.[88]Key policy areas and fiscal management
Menlo Park's housing policies have centered on addressing California's regional housing needs assessment, which mandates the city to plan for 1,662 units of affordable and below-market-rate housing by 2031, amid chronic supply shortages driven by restrictive zoning ordinances that limit multifamily development in single-family zones.[89] These constraints, including height limits and density caps, have contributed to median home sale prices exceeding $2.7 million as of August 2025, rendering ownership unattainable for median-income households and exacerbating regional displacement pressures. Local debates intensified in 2025 over proposals to redevelop three city-owned downtown parking lots into hundreds of affordable units, with residents organizing opposition groups like Save Downtown Menlo, citing concerns over reduced parking availability and neighborhood character preservation, effectively embodying NIMBY resistance that perpetuates supply inelasticity.[90] [91] A June 2025 ballot measure sought to require voter approval for such repurposing, highlighting tensions between state-mandated growth and local control, though similar anti-development initiatives have faced legal challenges under California's builder's remedy laws.[92] On public safety, city policies emphasize proactive measures like the Vision Zero Action Plan, adopted to eliminate traffic fatalities through infrastructure investments and enforcement, reflecting data showing preventable collisions as a leading local risk.[93] Policing strategies have focused on community-oriented models, credited with a 47% reduction in violent crime since implementation, alongside post-2020 reforms discussed in council forums to enhance oversight and equity without defunding core operations.[94] [95] Recent controversies include a 2025 investigation revealing unauthorized out-of-state sharing of automated license plate reader data by the police department, violating California privacy statutes and prompting internal audits.[96] Fiscal management relies heavily on tax revenues, with the FY 2024–25 general fund budget projecting $56 million—or 77% of total inflows—from property taxes, transient occupancy taxes, and sales taxes, supplemented by business license fees to cover operations without drawing on reserves.[78] The city maintains conservative budgeting practices, including cost recovery programs for development reviews and cash flow oversight to avoid deficits, though debates arise over balancing business retention incentives—such as streamlined permitting for tech expansions—with proposals for increased fees that could deter corporate relocations amid Silicon Valley competition.[79] These policies underscore a pro-growth orientation, yet face pushback in development approvals where fiscal benefits from new projects clash with resident-led slowdowns on infrastructure funding.Economy
Role in Silicon Valley innovation ecosystem
Menlo Park has played a pivotal role in the development of core internet technologies through SRI International, a research institute headquartered there since 1946. In the late 1960s, SRI hosted one of the four original nodes of ARPANET, the precursor to the modern internet, enabling packet-switched networking experiments that demonstrated feasible long-distance data transmission.[31] This work, conducted under DARPA auspices but leveraging private-sector engineering talent, laid foundational protocols for interconnecting disparate networks, influencing subsequent private innovations in computing and telecommunications.[32] The city serves as a nexus for venture capital, concentrating firms that provide equity financing to early-stage technology startups, thereby reducing reliance on debt or government grants and accelerating private-sector scaling. These hubs have facilitated the funding of thousands of ventures by aligning investor capital with entrepreneurial risk-taking, where founders retain significant control and upside from intellectual property.[97] This model contrasts with subsidy-dependent ecosystems, emphasizing market-driven validation over bureaucratic allocation, with Menlo Park's proximity to talent pools enabling rapid iteration from prototype to commercialization. Empirical indicators underscore this private-led dynamism: a 2016 analysis ranked Menlo Park among the top U.S. locales for patents per capita, reflecting high inventive output tied to inventor density rather than public funding mandates.[98] Strong enforcement of property rights, including patents and contracts under U.S. and California law, has causally enabled innovators to capture returns on R&D investments, while historically low regulatory barriers to business formation—such as streamlined incorporation and minimal zoning hurdles for tech offices—have lowered entry costs, fostering a multiplier effect where successful exits recycle capital into new ventures. This chain, rooted in secure ownership and minimal state intervention, has generated sustained wealth creation independent of centralized directives.Major employers and industry sectors
Menlo Park's major employers are concentrated in technology, research and development, and professional services, with a strong emphasis on AI, biotechnology, social media platforms, and applied sciences; these sectors overshadow traditional industries such as retail, manufacturing, or agriculture, which employ far fewer residents or operate on a smaller scale locally.[43] The city's proximity to Stanford University and its position within Silicon Valley amplify this tech-centric profile, drawing firms focused on innovation rather than commodity production.[99] Meta Platforms, Inc., headquartered in Menlo Park since 2011, dominates as the largest employer, with its expansive campus supporting social networking, virtual reality, and AI development; as of 2025, it employs 19,029 local workers, representing a significant portion of the city's job base amid company-wide headcount fluctuations from post-pandemic layoffs and rehiring.[100] SRI International, a nonprofit research organization founded in 1946 and based in Menlo Park, follows as a key player in R&D, with approximately 2,100 full-time equivalent staff engaged in projects spanning AI, biomedical engineering, and defense technologies as of recent reports.[101] Additional employers include Robert Half International, a staffing and consulting firm also headquartered in Menlo Park, which bolsters the professional services sector through talent placement in finance, technology, and administrative roles, though precise local headcounts remain undisclosed in public filings.[102] The Menlo Park campus of the U.S. Department of Veterans Affairs operates a medical center providing healthcare services, listed among county-level major employers but without specified employee numbers in available data.[99]| Employer | Primary Industry Sector | Approximate Local Employees |
|---|---|---|
| Meta Platforms, Inc. | Technology (social media, AI) | 19,029 (2025) |
| SRI International | Research and development (AI, biotech) | 2,100 |
