Clubs & Activities

St. Sebastian’s broad range of clubs provides students with the opportunity to discover and develop their special interests and talents. Whether behind the debate podium, or as a member of a musical performance, each boy grows in self-confidence and self-reliance as he finds the best in himself. Being part of a club also helps students develop an appreciation for the value of belonging to and participating in something larger than themselves.

St. Sebastian’s encourages students to participate in clubs, as well as sports, building time into the weekly schedule so that boys are able to pursue both. Athletic events, play practices, music rehearsals, student council programs, and other activities are, whenever possible, scheduled not to conflict. Students are often members of multiple clubs, and new organizations develop as student interests warrant.
