  • Jeffrey Thompson
    Head Coach
    Jeff Thompson has developed a simple, four-word motto over nearly two decades as a swimming coach: Grit. Resilience. Reliability. Ownership. These simple but powerful words guide Thompson’s vision as a swimmer, coach, teacher, and administrator.

    In the 2017-18 season, Thompson helped the GA girls swimming team to a fifth-place finish at Easterns. He coached five All-League Swimmers, four Easterns champions, two Inter-Ac League champions and one All-American during the year.

    Before coming to GA in fall 2014, Thompson spent 17 years as a USA Swimming Coach for the Terre Haute Torpedoes (IN) and 15 years as the head coach of the Terre Haute South Vigo High School boys’ and girls’ swim teams. With the Torpedoes, Thompson helped grow the club from 60 to 300 swimmers of all ages, as well as developed a learn-to-swim program and a Masters’ swim team. He has developed and mentored state champions, junior and senior national qualifiers, and sent swimmers to compete successfully at Division I colleges and universities. As the head coach of Vigo High School, Thompson led the team to its first boys’ sectional title in February 2010, while the girls’ team enjoyed 15 consecutive winning seasons. He also has experience in the planning, financing and building of two new pools in the Terre Haute area.

    Thompson earned his Master of Science degree in coaching from Indiana State University and a bachelor’s degree in math education from the same school. Thompson, who swam competitively at University of Illinois, Urbana, also earned a bachelor’s degree from the school in civil engineering.

    In his first year with the GA Varsity program in 2015, Thompson led the girls’ team to an Inter-Academic League title, and a fifth consecutive title at the Eastern Interscholastic Swimming and Diving Championships.

    In addition to his posts as Director of Aquatics and Head Coach for the GA varsity swim program and the Germantown Academy Aquatic Club (GAAC), Thompson also teaches 5th Grade math in GA’s Lower School.

  • Donald Brush
    High Performance Coach

    Joining GA in April 2015, Donny Brush brings to the program more than 20 years of experience as a professional swimming coach at the age group, high school, and collegiate levels. A native of Terre Haute, Indiana, Brush comes to GA after one year with the Fishers Area Swimming Tigers, preceded by nine successful years at Indiana University as Associate Head Coach for men’s and women’s swimming and Assistant Head Coach for the coordination of training and student athlete development.

    Throughout his time at IU and in prior coaching positions, Brush consistently develops strategies that improve both team and individual development, and takes extra steps to train the bodies and minds of his student-athletes. To briefly summarize his impressive coaching career, Brush has worked with more than 100 NCAA All Americans, three Individual NCAA Champions, 16 USA National Team Members, 15 Olympians (2016 - 2 Gold medals, 1 Bronze; 2012 - 1 Bronze), 12 American Record Holders, and 28 World Record Holders.

    Brush graduated with a bachelor’s degree in physical education from Indiana State University and also earned a Master of Science degree in student-athlete development from the same school.

    At GA, Brush will spend the majority of his time working with the senior-level student-athletes, but will also work in the pool with GA’s swim classes during the day.
