Welcome to St. Mary's

St. Mary’s School is a private International Baccalaureate (IB) World School, offering Preschool through Grade 8. It is the only private school of its kind in Orange County. As one of the area’s premier independent schools, we succeed because of our outstanding faculty, innovative curriculum, small class sizes and unique community. Innovation is at the heart of our philosophy.

As an (IB) World School, we believe children learn by doing, and we use inquiry as a driver for all that we do. Our learning spaces reflect our flexible, individualized approach to a school environment. Under the compassionate guidance of world-class faculty, we foster independent thinking and spark imagination. Our goal is to prepare and inspire our children to become the leaders of tomorrow.
