Activities & Organizations

castilleja school ace org gatorbotics

Castilleja students have dozens of clubs and co-curricular opportunities to choose from. Through these student organizations, girls learn, engage, have fun, and develop hands-on leadership skills.


Many students have started organizations that engage their peers in community action and raise global awareness. Students also lead academic and arts clubs that travel to compete or perform.

Castilleja’s unique schedule has a Community Time period during the regular school day designated for these student-initiated learning and leading opportunities.

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.
