Head Coach Shari Cruse

In the past two years she has competed in 2 sprint triathlons and over 20 running races, including 7 half marathons.

Shari has a B.S. degree from the University of Chicago in Behavioral Science, a Masters degree in the Science of Teaching from the University of Chicago, and is a lawyer with a J.D. from Golden Gate University Law School.

She taught music lessons for 15 years and taught elementary school kids in the Chicago Public school system, and then here in Marin.  Shari loves being on deck helping other Masters swimmers enjoy the same wonderful experience she has had. She strives to help people with their proficiency in swimming, but also wants to help them attain a terrific sense of accomplishment, increased fitness, confidence to challenge themselves in other sports, and, most of all, the opportunity to make great lifelong friendships.

Coach Sarah Jack

sarahSarah joined our coaching staff in October 2016. She has a rather humorous approach to life as well as her bio here with “25 things you absolutely must know about Coach Sarah”

The 25 things you must know. 1) She learned to swim at 9 months old and 2) at age 9 in a race she decided it was too long and climbed out of the pool midway through. 3) Growing up, the trophy she always wanted was the biggest one – the “Most Coachable” trophy. 4) Not only did she never get that trophy, her name was probably never mentioned. 5.) She hates fins and breaststroke equally. 6.) She started coaching swimming at age 16. 7.) No need to do the math, but that’s 22 years of coaching and or teaching swimming to all age groups and abilities. 8.) She feels most at home in the water. 9.) She loves the ocean, and will swim in it, but she will hate every minute of it. 10.) This goes for any body of water sharks can enter. 11.) Open water swimming in fresh water is her favorite. 12.) The only person she knows that gets injured more than herself is Coach Cokie. 13.) Swimming has been her one saving grace during every injury. 14.) She coaches and will continue to coach swimming because it is the bestest thing ever. 15.) Her love of swimming probably started at the age of 12, right about the time she realized she was naturally good at it. 16.) Chlorine is her favorite smell. 17.) The sound of someone swimming freestyle correctly is probably her favorite sound. 18.) She often spends half her workout analyzing the other swimmers around her. 19.) Butterfly is her favorite stroke. 20.) She can only breath to one side. 21.) The left side, because when she was young a coach told her right handed people breath to the right, she wanted to prove them wrong, suckers. 22.) She has 3 boys 15, 13, & 10. 23.) She swam through every pregnancy. 24.) When she’s not coaching she’s teaching mindfulness to children. 25.) Most importantly she doesn’t take herself too seriously.

Coach Buffy Patterson

Buffy PattersonBuffy joined our coaching staff in June 2014. She is a USMS Level 2 certified coach.

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 a few 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
