In the Company of Girls


It's about the remarkable presence of girls, not the absence of boys.


Every aspect of Castilleja’s collaborative and hands-on curriculum is facilitated by faculty, coaches, and advisors who are well-versed in the way girls analyze and synthesize information. This supportive environment allows Castilleja girls to take risks, tackling our challenging curriculum with boundless curiosity. Together as peers in learning, our students nurture and mentor each other to build braver aspirations.

Castilleja girls have the freedom and support to ask questions with abandon. They can explore fearlessly, confident in the guidance from our community and the strength of their connection to peers. At Castilleja—and in the company of girls—every opportunity is hers to seize.
