Castilleja was founded in 1907

to be a great equalizer for women.

We made space for girls to be themselves. To experiment and build. To create and innovate in their own way. To discover new truths about themselves and the greater world. Today requires more—our inspiring mission met with a new vision of what can be and should be. We are called to make new spaces for their brilliance, create new ways for them to take the lead, and open new doors of opportunity.

Open Their World—The Campaign for Castilleja will continue to shed light on all that is possible for the future of women's education and leadership.

A Space to Learn to Lead

Multi-use hubs will foster collaboration and community. Makerspaces will encourage hands-on critical thinking. Integrated wellness spaces will develop resilient students. And the interdisciplinary labs, like the teaching kitchen and recording studio, will deepen learning and collaboration. By revolutionizing their spaces, we're empowering our students to revolutionize the world.

A Living Laboratory for Sustainability

Environmental consciousness is part of the Castilleja fabric, so it's only natural that our new campus will be a model for resilient, sustainable, highly efficient design—a facility that will empower the next generation of changemakers with the knowledge, hands-on experience, and agency to co-create sustainable solutions.

A Promising Future

This plan advances everything that is already remarkable about Castilleja: Transformative faculty; changemaking students; collaboration that nurtures leadership and critical thinking; and a commitment to accessibility. By creating a more dynamic learning environment for future women leaders, we're ensuring limitless possibilities for our program, promise, outcomes, and impact.

Suzanne and Eric O'Brien P'21 (Alum Parents)

After attending a co-ed middle school, our daughter quickly recognized the unique benefits of the Castilleja mission when she entered as a 9th grader. Watching her grow as a leader alongside her inspiring classmates affirmed our support for the capital campaign to reimagine the campus. We're excited to see the next generation of leaders thrive on their new campus.

Supporting this campaign extends beyond our gratitude for what Castilleja has meant to our family—we view Open Their World as an opportunity to support women's education and the future of women's leadership.

Our daughter's experience at Castilleja has been truly transformative. We've watched our shy, hesitant girl become a leader in a way uniquely authentic to her. She's grown into a confident and thoughtful speaker and someone who is eager to engage with everything around her.

As we imagined the generations of future students graduating from Castilleja, each with the experience that our daughter has had, each ready to make a difference in the world in whatever they choose to do – of course we wanted to be a part of that.

Andie Sobrato '08 (Alum)

What inspired me to support this campaign was my desire to give back to the institution that gave me so much. During my seven years at Casti I had the opportunity to learn from engaging teachers, participate in sports that taught me about teamwork and listen to amazing speakers from around the world. When I reflect about my value system, I know I undoubtedly got so many of them from Castilleja. In addition to the values, I found life-long friends that are supportive, fiercely driven in their pursuits and incredible citizens of the world. As an alum who received financial aid during my time, I feel it is my turn to support this school that provided me with so many opportunities. Ultimately, I want to be part of creating transformative experiences for the next generation of young girls and pay it forward as generous donors did before me.
