Greetings from the Head of School

Since 1950, our school has remained true to the founding principles expressed in our Motto, Mission, Vision Statements, and in the underlying message Do Well. Do Good. You will enjoy, though, the current expression of these values in a world that changes almost hourly. Santa Catalina offers challenge. We expect responsibility, and we work diligently to pursue ever-increasing avenues of service to others. You will see that all this takes place in a community that is friendly and open, spirited and creative — a place where you will share and learn comfortably, make friends for a lifetime, and become your best self.

Please join us for a visit. Meet our students and faculty and share a day on the campus. We look forward to meeting you and to sharing with you a glimpse of what you might become with us in your life’s journey.

With warm regards,

About Us

Santa Catalina is recognized for its excellent academic programs and its legacy of developing self-assured young women and men of intellect, compassion, and distinction. Established by Dominican Sisters in 1950, Santa Catalina’s teaching philosophy has always been the same: To develop students’ intellectual curiosity along with their spiritual, moral, creative, and physical talents.


In this time of unprecedented change, our philosophy is guided more than ever by a strong belief in the promise of young people to shape a better future. Our goal is to foster reflective, open-minded students prepared and motivated to make a difference in our increasingly international 21st-century culture.

Today, Santa Catalina alumni can be found at the nation's top universities and in leadership positions in virtually every walk of life. No matter where their lives take them or what their roles are, Santa Catalina graduates are forces for change in our world.

We hope this website will give you an idea of the quality of education we provide and invite you to visit our beautiful campus to see what makes Santa Catalina stand out as a uniquely warm and vibrant community.

We look forward to meeting you!
