The Martinez Community Swim Team welcomes you to our 2022 swim season. We are very excited to see our returning swimmers back in the water and welcome our new Otters to the MCST family. The Otters have been an active part of the Martinez community since 1980. We are hopeful that Contra Costa County regulations will allow us to enjoy a much-anticipated season in the beautiful Rankin Aquatic Facility in downtown Martinez. Our team has grown substantially over the past several years with the help of an experienced volunteer parent board of directors and a well qualified professional coaching staff. Please continue to monitor our website for information about sign-ups or reach out to head coach Keelan Kirshen or any member of the Board for information. Go Otters!
