Bio entering the 2017-18 season

Jeff Thomsen is in his eighth season as an assistant coach for the San Diego State men's tennis team. His philosophy of developing each player's unique playing style has been a valuable addition to the Aztec staff.

Thomsen has had a tremendous impact in his first seven seasons on The Mesa, coaching nine 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. In addition, Thomsen has tutored seven all-MW doubles tandems during that span.

A native of Newport Beach, Calif., Thomsen also played an integral role in helping SDSU win 12 straight regular-season conference matches from 2012-14. In that stretch, the Aztecs claimed the 2013 Mountain West regular-season championship for the program's first title in six years.

Prior to his arrival at San Diego State, Thomsen spent three years with the women's tennis team at the University of Miami from 2007-10, where he served as the associate head coach his final season after serving as an assistant the previous two campaigns. With Thomsen on staff, the Hurricanes achieved a No. 10 national ranking at the end of the 2010 season.

During his tenure at Miami, Thomsen was responsible for organizing practices and assisting with recruiting. One of his first recruits, Gabriela Mejia, earned All-America honors at the end of the 2010 season. He was also influential in the development of Laura Vallverdu, who advanced to the finals of the 2010 NCAA singles championships.

Prior to his stint with the Hurricanes, Thomsen served as head coach for one season at Orange Coast College in Costa Mesa, Calif. With the Pirates, he quickly turned around a struggling team and led them to a top-eight finish in the final JC rankings.

Before his brief tenure at OCC, Thomsen was head boys varsity coach and head girls junior varsity coach at Newport Harbor High School. He made the most of his opportunity, transforming the school into a dominant tennis program while taking the boys varsity team to the California Interscholastic Federation (CIF) Southern Section playoffs in four of five years. Even more impressive, he guided the girls team to three undefeated seasons from 2002-05.

Thomsen is also a highly sought-after personal coach, spending six years as a private instructor in California mentoring professional players as well as nationally-ranked juniors. In February of 2000, Thomsen co-founded the Latin American Sports Camp in Buenos Aires, Argentina.

Thomsen played at the collegiate level for Golden West Junior College in Huntington Beach, Calif. After reaching a No. 1 ranking in the state, he received a scholarship from University of Oregon. Thomsen earned two letters with the Ducks before graduating in 1999 with a degree in sociology.
