Student-Led Organizations


Castilleja students have dozens of clubs, interest groups, and co-curricular opportunities to choose from. Through these organizations, students learn, engage, have fun, and develop a better understanding of themselves as leaders.


ACE Orgs are Castilleja’s student-led and student-driven social impact teams. This program provides a framework for students to cultivate awareness, build empathy, develop skills, and generate impact to create a generation of informed and motivated young leaders equipped to address social and environmental issues and effect change in the world. ACE Orgs are proposed, designed, and led by sophomores, juniors, and seniors, and participation in one ACE Org is required of all US students

The list below is a sampling of some of these organizations. Student Activities & Organizations are truly student-led and student-focused, so naturally opportunities change year-to-year with interest.
