Marc Detraz
Aquatics Program Director

Originally from the French Alps, Marc began swimming competitively for a summer league team at the age of 9. At 15, he began swimming year-round when he was recruited to swim in the regional training center with national and international level athletes and was coached by Marc Begotti.

As a swimmer Marc specialized in sprint freestyle events, but developed an affinity for open water swims and eventually for triathlons. At Grenoble University, Marc swam competitively for three years while studying Physical Education.

Marc was a Physical Education instructor during his French military service before moving to Mill Valley in 1991. He spent a few year teaching swimming at the Marin JCC with Jeff Kamler and got his first local coaching job with the Rolling Hills Stingrays, a Marin Swim League team.

Marc began coaching the Marlins in 1994, when the team belonged to the Marin Swim League. With the help of Coach Sonia Nimtz, he quickly turned the team around by focusing primarily on technique.

In July 2000, Marc received the Marin Swim League’s Coach of the Year Award and redesigned the Rafael Racquet Club Marlins to a year-round United States Swimming program. Now called the Pacific Coast Marlins, the team continues to succeed under Marc’s dedication and coaching philosophy.

Buffy Patterson
Assistant Swim Coach / Lifeguard Supervisor

Buffy grew up in San Rafael; she started swimming in the Marin Summer league for the Marin wood water devils at the age of 5. She attended Terra Linda High School and swam varsity for all four years (she also played water polo and basketball). She continued to swim and play water polo at San Diego State University where she got a B.S. in Recreation Administration. Her main events were the 200 & 500 freestyle. Buffy enjoys most activities that take me outside like swimming, biking, running, skiing and hiking.

Buffy started to help children learn how to swim at in her early teens as a swim aide at the Marinwood pool and continued on to be a swim instructor teaching students of all ages and abilities all through High school and is still currently teaching at the JCC. She got her first coaching position in the Marin Summer League with the Novato Riptides and is very excited to be part of the Marlins.

In 2013, Buffy took on an additional role at RRC as the Club’s Lifeguard Supervisor; expertly leading our summer staff.
