San Domenico Aquatics

San Domenico is close to completion of a new Aquatic Complex that will provide best-in-class facilities for swimming and water polo competition, physical education, conditioning, and wellness for our K-12 program. The new facility will include a 4,300 square foot pool deck, spectator seating, showers and locker rooms. Phase I construction is expected to last about seven months. The new competition pool has been designed by Aquatic Design Group, one of the top aquatics architectural firms in California who designed competition pools for UC Berkeley and Stanford University.

Phase II of the project will be the completion of a new 2,000 square foot Community Center providing flexible teaching, meeting, and community gathering space on the west side of campus for the first time. The complex has been named for Sister Gervaise Valpey, a beloved and influential figure in the San Domenico community.

Please check back with this site for periodic updates on project progress. For more information about how you can become involved, please contact Anna Heidinger, Director of Advancement at aheidinger@sandomenico.org.

WATER POLO COMING TO SAN DOMENICO IN 2021!

Mark Anderson

San Domenico is in an exciting transitional period for our aquatics programs. We are in the process of building a new and much needed state of the art pool to accommodate regulation size water polo and swim programs. Our vision is to provide seasonal swimming and water polo programs and camps for our student body and to have a competitive JV and Varsity High School Swim Team and Water Polo Team. We are excited to have Aquatics Director Mark Anderson leading this vision, taking our school to new heights in opportunities and competition.

Mark is Head Coach of the 25-time Marin Swim League Champions, Sleepy Hollow Swim Team. His company, Maaquatics Inc. provides seasonal swim lessons and swim team programs for kids ages 5 to 18 in our community. He is also co-founder of SHAQ Water Polo Club offering competitive age group programs for kids ages 8 to 18 in our community. Mark has coached the Boys Drake High School Varsity Water Polo Team to seven MCAL Championships. In 2017 and 2018, 36 of Mark’s athletes went on to play for Division I Colleges and Universities. Mark was inducted into the Marin County Athletic Hall of Fame in 2014 and brings with him not only a history of success in building programs, but also a strong commitment to building community.

“The San Domenico campus is in my backyard and I already coach so many SD kids. It’s like an extended family. To have the chance to train total athletes, K-12, to work on mind-body, health and wellness, using aquatic strength and conditioning, it’s very exciting to be a part of building this program and to help shepherd in this new era of aquatics at San Domenico.”- Coach Mark Anderson

Together with his wife Julie—also a coach—as well as Coach Matt Swanson, Mark runs our High School JV and Varsity BCL Swim Teams and works with students K-12 on physical education and seasonal, water-based conditioning and training for our athletic teams across the board. Mark, Julie, and Matt are excited to share their passion for swimming and water polo with the San Domenico community.
