Sergey Avdeyev serves as Assistant Coach for Oklahoma State University's Men's Tennis program in Stillwater, Oklahoma. Avdeyev came to Stillwater ahead of the 2024-25 season. He now leads the program as interim head coach, adding ten years of NCAA Division I coaching experience to the Pokes staff.
Avdeyev's first head coaching gig came in 2019 at the University of Texas San Antonio Men's tennis team. While at the helm, Avdeyev was named 2023 Conference USA Coach of the Year, posted a 58-43 record in his five seasons and broke many school records along the way: their highest team ranking (34), their first-ever NCAA at-large bid, most consecutive wins (14), highest-ranked win (No. 28 VCU), doubles regional champions, highest-ranked doubles team (#6 in the country), highest home match attendance, and most conference awards. Avdeyev's leadership goes far from just the tennis courts, as he served as the UTSA Game-plan Committee Chair (Student-Athlete Experience) in 2022-23, the San Antonio International Pro Exhibition Tennis Tournament Supervisor in 2023 and ITA Texas Regional Committee Board Member 2022- 23 and Chair in 2023-24. In 2016, Avdeyev was named Men's Associate Head Coach for the Old Dominion University tennis team.
