Swimming has been a lifelong passion for Aaron.  He grew up swimming for the Ygnacio Wood and the Terrapins Swim Team in Concord.  Aaron earned his bachelors degree from the University of Hawaii at Manoa, where he was also a member of the swim team.  He went on to finish his teaching credential at Chapman University and currently teaches Physical Education at Diablo View Middle School in Clayton.

Aaron has coached for local swim teams such as Rudgear Estates, Terrapins and Valley Vista for 18 years.  While some of Aaron’s success as a head coach may be measured in City Meet wins, his philosophy is founded on the balance of proper technique, hard work, and fun.  He believes the most important part of recreational swimming is the family and friends met and created throughout the years.

In his free time, Aaron enjoys keeping active; surfing, golfing and swimming with the Walnut Creek Masters team.
