Clubs
At Damien High School, student clubs play a vital role in shaping a well rounded and engaging campus experience. With more than forty active clubs – and the opportunity for students to create their own – our offerings allow every Spartan to pursue academic interests, explore social justice initiatives, participate in service, discover new hobbies, and connect with peers who share similar passions. These clubs enrich daily life on campus, strengthen our sense of community, and encourage students to grow as leaders, deepen their faith, and contribute meaningfully to the life of the school.
