An independent day school for grades 6-12
CSUS relies upon thousands of hours of volunteer support from families. There is a variety of volunteer opportunities to choose from — long-term leadership roles (serving as a trustee, chairing an event like the Gryphon Gala) to smaller time commitments (driving on a field trip, providing food for an event). There is a volunteer job to fit everyone’s availability and interests - from the Fine Arts Collective and Gryphon Club (athletic boosters) to Admission's Open House and the Advancement Office's Annual Fund to Community Service efforts and the school's Global programs.

When parents contribute their time, expertise or talent, the school thrives.
