Jeff Thomsen serves as Associate Head Coach for San Diego State University's Men's Tennis program in San Diego. The San Diego State source profile describes Thomsen's current role and recent program context, including that Jeff Thomsen, who was elevated to associate head coach in August 2019, is in his 16th season with the San Diego State men's tennis program. A native of Newport Beach, California, Thomsen has had a tremendous impact in his first 15 seasons on The Mesa, coaching 14 different all-Mountain West singles performers, including Javier Pulgar and Freddy Gelbrich, who each captured the league's player of the year award in 2012 and 2015, respectively.
The same profile adds background on Thomsen's coaching path, team results, and player-development record. In 2025, Thomsen helped lead three Aztecs to all-conference honors. Thomsen was a critical part of San Diego State’s successful 2024 campaign in which the Aztecs went 16-7 and captured a Mountain West Championships runner-up finish. Despite an undermanned roster that was heavily impacted by graduation from the previous year as well as the lingering COVID-19 pandemic, two SDSU newcomers flourished under Thomsen’s influence during the 2021 spring season, as Johannes Seeman garnered all-Mountain West accolades in singles and joined forces with Victor Castro to receive all-conference doubles recognition. For the ICDB record, that background gives readers a fuller picture of the experience Jeff Thomsen brings to the Men's Tennis staff.
