During his time at UCSD, a Division II non scholarship program competing against Division I scholarship programs, the Tritons ended the season ranked fifth in the nation. They beat perennial powers USC, UCI, UCSB, Pepperdine, Long Beach State and UOP. In 2002, the Tritons won their 13th Western Water Polo Association championship and qualified for the NCAA Final Four.

His first goal of every swim season is to help each student-athlete transfer to a four year university to get their degree.
