Early life
Cooper Williams was born on June 17, 2005, in New York City, United States.[1] Williams began playing tennis at age four at the Manhattan Tennis Club. He was raised in Manhattan, where he spent the majority of his early years before relocating to Florida, specifically the Boca Raton area, during the COVID-19 pandemic.[8][9] This relocation supported his early development in tennis training at the USTA center there.[8] Public details about Williams' family background, including information on his parents or siblings, remain limited and not prominently documented in available sources.Education
Cooper Williams attended St. Bernard's School, a private institution on Manhattan's Upper East Side, for his early education from kindergarten through seventh grade.[8] In eighth grade, Williams enrolled in the Dwight Global Online School, an accredited online program affiliated with Dwight School in New York City, to accommodate his intensifying tennis commitments that often required extensive travel and missed in-person classes.[10][11] He graduated from the program in June 2023.[10] The flexible structure of Dwight Global, which featured asynchronous classes and adjustable deadlines, allowed Williams to maintain academic rigor while prioritizing morning training sessions and international tournaments.[10] Following his family's relocation to Florida during the COVID-19 pandemic for access to advanced tennis facilities, Williams continued his education through the online format, incorporating homeschooling elements such as self-directed study and personalized faculty support to balance his schedule.[8][10] This approach not only ensured continuity in his academics but also fostered time management skills essential for his dual pursuits.[10]Tennis career
Junior career
Cooper Williams began playing tennis as a child in New York City, where he grew up near the USTA Billie Jean King National Tennis Center. Initially, he trained informally by renting public courts after school with his mother and practicing for about 90 minutes three times a week against local college players, without joining a formal academy.[12] Williams rose quickly in the junior ranks, competing in USTA events and achieving national prominence early on; at age 12, he won the 2017 USTA National Junior 12s doubles title partnering with Alan Hua. By 2023, he had become the top-ranked American junior and reached a career-high ITF junior world No. 3 in singles, establishing himself as one of the leading prospects in the under-18 circuit.[13][8][2] In 2023, Williams made his junior Grand Slam debut at the US Open as the top-seeded American boy, advancing to the quarterfinals in singles while showcasing his development on the international stage. That year also marked a capstone in doubles, where he partnered with Learner Tien to win the Australian Open boys' title.[8][14]Professional career
Williams turned professional following his high school graduation in June 2023, transitioning from a successful junior career to competing in senior events on the ITF World Tennis Tour and ATP Challenger circuit. His first notable professional appearance came in November 2023, when he qualified for the main draw of the Champaign-Urbana Challenger by defeating higher-seeded players in the qualifying rounds.[15] This marked the start of his efforts to build ranking points outside of college commitments. Williams achieved a career-high ATP singles ranking of No. 660 on September 29, 2025, reflecting steady progress through consistent performances in lower-tier professional tournaments. In doubles, he reached a career-high of No. 473 on September 8, 2025.

The pair advanced to the second round with a first-round victory over Petr Nouza and Patrik Rikl, 7-6(7), 6-4, before falling to the experienced duo of Kevin Krawietz and Tim Pütz, 3-6, 4-6. This performance highlighted his growing competitiveness at the professional level.[17][18][7] By late 2025, Williams had amassed approximately $50,974 in career prize money from professional events, underscoring his transition from junior standout to emerging pro contender with a focus on doubles partnerships and hard-court proficiency. His overall professional singles record stood at 18 wins and 6 losses for the 2025 season alone (as of November 2025), primarily on hard courts.[1][19][20]College career

He compiled a 17-10 overall singles record, including 8-6 in dual matches, 2-2 in Ivy League play, 3-1 in NCAA tournament action, and 6-3 in the fall season, with 10 wins against ranked opponents. In doubles, he posted a 25-13 overall mark, with 12-10 in dual matches, primarily partnering with Daniel Milavsky. His performance earned him ITA All-America honors in singles, making him the first Harvard freshman to achieve this distinction since James Blake in 1998, as well as the 2024 ITA National Rookie of the Year. He was also named to the unanimous First Team All-Ivy League in both singles and doubles, reached the NCAA singles quarterfinals (the first Harvard player to do so since 2014), and advanced to the 2024 NCAA Individual Championships in both singles and doubles, achieving career-high national rankings of No. 9 in singles and No. 4 in doubles. Following his standout freshman year, Williams transferred to Duke University ahead of the 2024-25 season. As a sophomore, he anchored Duke's lineup with an 18-11 singles record (12-7 in dual matches) and led the team in doubles with 24 wins (24-8 overall, 19-4 in dual matches), partnering primarily with Theo Winegar for 19 of those victories. The duo went 8-0 against ranked opponents, contributing to Williams' No. 3 final ITA doubles ranking and No. 53 in singles. He also received ITA Doubles All-America honors, All-ACC Third Team in singles and First Team in doubles, and was selected to the 2025 CSC Academic All-District Team, highlighting his balance of tennis and academics.
