Coaching Staff


Let’s tell you about our award winning coaching staff: Head Coach Cokie Lepinski & Coaches Susie Powell, Shari Cruse, Buffy Patterson, Marlon Woolf and Nicole Coll. 

Cokie and Susie have been friends since 1999 when they met on their first swim team, the Rolling Hills Mud Sharks. In 2007, Cokie & Susie got the bug for coaching and began designing and coaching swim clinics for adults. They both realized that they really, really enjoyed doing this, and both got involved in coaching in different ways. Cokie founded a new masters team, the Marin Pirates Masters, and became very involved with Pacific Masters Swimming, serving as Coach’s Chair from 2010 through 2013 and also serving on the USMS Coaches Committee. Meanwhile, Susie started giving swim lessons to adults, first one-on-one, and then with a swim exercise program, SwimFit, at Rolling HIlls Club. In SwimFit, Susie taught adults swim technique, how to read the pace clock, how to do swim sets and much more! Her SwimFit has been going strong since 2010 with many loyal followers. In the fall of 2010, she joined Cokie on deck as an Assistant Coach with the Marin Pirates Masters and then continued the journey together with the advent of the Swymnuts team.

Growing up in San Rafael, Buffy started swimming in the Marin Summer league for the Marinwood Water Devils at the age of 5. She attended Terra Linda High School and swimming was the one sport where she was varsity for all four years. She also played water polo and basketball. Buffy continued to swim and play water polo at San Diego State University where she obtained a B.S. in Recreation Administration. Her main events were the 200 and 500 freestyle. Most recently, she enjoys activities that take her outside….swimming, biking, running, skiing, hiking, etc.

She started to help children learn how to swim when she was 12 or 13, serving as a swim aide at the Marinwood pool, and continued on as a swim instructor all through high school. Before leaving the area, she got her first assistant coaching job in the Marin Summer League, with the Novato Riptides. After a hiatus away from the water, she returned to it in 2010, getting back in to teach once again. “I knew it was time to get back into coaching!”   At the Marin JCC, Buffy instructed people of all ages and abilities. She is now in her third year of being an assistant coach for the Pacific Coast Marlins, a USA swim team located at the Rafael Racquet Club.

Buffy first got into Master’s Swimming in 1999 and was in and out of the pool the next few years. When she got back into teaching 4 years ago, she wanted to learn more about all things related to swimming. She has been taking many certification classes through ASCA including the USMS Level 1 & 2 Masters certification. She assisted the instructor at the JCC in a program very much like a Master’s club and enjoys working with all ages to support their passion for being in the water.

  1. Hi Cokie I found your article on breaststroke in Swimmer magazine very informative. I was wondering if you give private or group lessons on breaststroke. Thanks, Craig 510 326-6255
