We are grateful for your interest in learning more about a St. Joseph’s Academy education. We are a Catholic college preparatory high school for girls centrally located off of Highway 64 and Lindbergh Boulevard. Our young women are challenged to grow academically, in their faith, and explore their gifts and talents to become their most authentic selves in preparation to go out and make a profound impact in the world.

Founded by the Sisters of St. Joseph of Carondelet in 1840, the community of St. Joseph’s Academy is guided by the Sisters’ charism to live in right relationship with one another and “serve God and the Dear Neighbor without distinction.”  With this calling, we foster a welcoming school environment where students can take rigorous college-level course work, develop broad perspectives in unique courses to the Academy, run a business, join a robotics team, explore their creative selves, help plan a liturgy and join together in prayer.  Our legacy of excellence can be found in many areas of student life: in the classroom, on the field, on the stage, and in our new College Advising and Resource Center.  St. Joseph's Academy students are educated by caring faculty who motivate young women to think critically and creatively, while being free to be themselves.

Come visit us to experience the spirit of our school motto, “Not I, but We.”
