Mark is a renowned Swimming and Water Polo Coach, actively coaching for over 30 years in Marin. He arrived at San Domenico from his position as Head Coach of the 25-time Marin Swim League Champions Sleepy Hollow Swim Team. He also serves as the Co-Head Coach of SHAQ Water Polo Club. Previously, Coach Anderson led Drake High School Water Polo to seven MCAL Championships, and in the 2017 and 2018 academic years, 36 of Mark’s athletes went on to play for Division I colleges and universities. Mark was an All-American water polo player at College of Marin.
Mark was inducted into the Marin County Athletic League Hall of Fame for Coaching in 2014, and brings with him not only a history of success at building programs, but also a strong commitment to building community. Even with his success, Mark's focus is always on the overall health and well being of his scholar athletes. “We don’t talk about winning,” he is often heard saying to athletes and parents. “We talk about taking care of the kids and the winning often comes out of that.” Mark and his wife Julie both grew up in Marin and are local residents of Sleepy Hollow.
