Senior Group Coach


Hi! I am Randy Gertenbach and I coach the Senior Group. I started swimming competitively at the age of 8 in El Centro, CA, with Imperial Valley Desert Aquatics. I swam club and high school, which paved the way for me to swim in college at the University of Pittsburgh.  At University of Pittsburgh, I was an 11-time Big East Champion, which ranged from the 100 and 200 breaststroke, and 200 IM.  I qualified for NCAA’s in 2002, 2003, 2004 and was a 3 –time All American in the 200 breaststroke.  After graduating from the University of Pittsburgh with a Bachelor’s degree in Applied Mathematics, I then pursued my Master’s Degree in Educational Leadership and Cross-Cultural Teaching Techniques at the University of California, San Diego.  I am currently a High School Math Teacher, as well as being an assistant swim coach on this amazing team!!

My coaching philosophy is commitment, teamwork and pride in what you do will can take you anywhere. I believe that we are all “teachers” when it comes to swimming, and we learn and grow every day.

I am a person that loves to give back to his friends and community, and coaching swimming is something where I can do give back to both.  I love that I am able to share my love of swimming with our athletes. Swimming has shaped me and my individualism, and I feel it can do the same for our present and future swimmers
