Whether you are familiar with Castilleja or are learning about us for the first time, we hope you sense the wonder and possibilities that we see every day on campus.

Castilleja is brimming with possibilities. At its heart, Castilleja is a sisterhood of students and alumnae who are curious, kind and eager to learn. New students arrive with their stories still unwritten, and then the magic of an all-girls school unfolds: without gender biases, girls are empowered to lead, to deeply explore subjects they love, and to form friendships that will last a lifetime. They graduate as young women with confident voices and courageous imaginations.

Our admission team is eager to connect with you personally, help you navigate the admission process, and learn about “What’s Possible?” for you at Castilleja. To request a viewbook and be added to the Admission mailing list, please click here.
