Brentwood SeaWolves was founded in September 2007 by six families, with the first practice held in February 2008 with 12 swimmers, and it became a 501c3 non-profit organization in June 2009. The program’s mission states that it provides a safe, supportive and positive environment for all members, encourages community, family and individual participation at all levels, and fully supports all measures adopted by the US Center for Safe Sport and USA Swimming to protect athletes from abuse or mistreatment. The organization was founded to provide training, instruction and encouragement for increased proficiency in competitive aquatic sports and to further interest, education and participation in these sports in the community. Brentwood SeaWolves is a year-round competitive swim team and a member of USA Swimming, and its swim and water polo teams are sanctioned members of USA Swimming and USA Water Polo in the Pacific Swimming Zone 2. BSW swimmers consistently rank in the top 25 for Pacific Swimming, which includes more than 16,000 swimmers from 120 clubs in Northern California and Nevada. The program states that it has highly qualified coaches skilled at instructing all ages and abilities and offers programs from novice up to national levels, including athletes who have competed at Regional and National level (Olympic Trials) and at the age group Junior Olympics level. It is the longest running USA Swimming and USA Water Polo team in its area, offers both sports under one team, and offers part-time programs on a limited basis for many swim groups. Brentwood SeaWolves also has a year-round water polo program through a partnership with Lamorinda Water Polo Club, and Lamorinda-Brentwood Water Polo and the City of Brentwood offer Splashball as an introduction to water polo for kids ages 5–9. The team holds an annual summer potluck and organizes group activities such as ice skating, movie nights, and tie-dye shirt projects.
