Welcome to Santa Catalina School!
It is my honor to serve as the fifth Head of School at Santa Catalina, a community built on more than seven decades of educational excellence, faith, and a deep commitment to nurturing the whole student. This legacy—rooted in the vision of pioneering women who believed in the power of purposeful learning—continues to inspire and inform all that we do today.
Santa Catalina instills in its students courage, grace, compassion, and respect. Our foundation emphasizes the values of openness, service, and meaningful relationships. We believe that education should cultivate both intellect and character. In our teaching, we stress the importance of integrity and affirm the dignity and worth of each individual, ensuring every student feels a sense of belonging in the Catalina community. Both faith and reason serve to guide our search for the truth. At the heart of it all is a steadfast belief in our students—often, we believe in students before they believe in themselves.
Our Lower and Middle School serves boys and girls from PreK through Grade 8, offering a nurturing environment where curiosity and creativity flourish. The Upper School—a dynamic, all-girls day and boarding program for Grades 9–12—is where young women grow into confident learners and compassionate leaders. Across all grade levels, expert faculty design immersive learning experiences that are deeply personal and intentionally student-centered. What sets a Santa Catalina education apart is the strength of our relationships and our commitment to helping students become the truest version of themselves—young people who understand their place in the world, take responsibility, serve the world, and lead lives of meaning and purpose.
While this website offers a glimpse into the Santa Catalina experience, the true spirit of our school is best felt in person. From joyful classrooms and inspiring teachers to an engaged parent community and passionate alumnae/i, there is something remarkable around every corner of our campus.
We look forward to welcoming you.
Come visit and experience the joy of Santa Catalina for yourself!
