Chesterbrook Swimming and Tennis Club (CST), established in 1954, is owned and managed by its members. The club has a friendly and active membership that participates in a variety of programs including tennis, swimming, and diving teams, and social activities for all ages. The pool opens usually on Memorial Day weekend and closes on Labor Day weekend. Tennis facilities may be used all year, weather permitting. Social activities are planned to bring the members together throughout the summer. Past activities include raft parties with pizza for children, Sunday brunches for adults prior to noon opening, and a mid-summer family barbecue, theme parties and 4th of July extravaganza planned by the pool lifeguards for families.
