Santa Catalina School is a private school in California founded by Sister Margaret Thompson and the Dominican Order in 1950. Situated on 36-acre hacienda-style campus, the Upper School is an all-girls boarding school which also accepts local students. The Lower School serves both boys and girls (Preschool through 8th grade). Students in both the Upper and Lower schools are required to wear uniforms. The school emphasizes building a sense of community that challenges its students mentally and spiritually.
