Founded in 1858, Mount Saint Joseph Academy is a Catholic college preparatory school for girls that inspires its students to dream big and journey deep.

Choosing the Mount means opportunities that empower students to lead and serve with compassion. Supported by a solid academic, social and spiritual foundation, young women at the Mount have powerful voices, clarity of mind, confidence and a commitment to the serve. A personalized and dynamic curriculum allows our students to engage in collaborative STEM learning, enroll in “Women as Founders”—a course that allows students to educate and advocate for social change—compete on the athletic field and much more. At the Mount you can find your sisters and find yourself.

Our Philosophy

The philosophy of Mount Saint Joseph Academy reflects the mission, charism, and tradition of the Sisters of Saint Joseph, empowering students to be agents of unity and reconciliation in the world. Although the philosophy is rooted in the past, the members of the school community remain mindful that they live in the present with minds and hearts set toward the future. Mount Saint Joseph Academy endeavors to create a climate in which all can more easily discern truth, love goodness, seek justice, follow right reason, and pursue a sustainable future which reverences God and all creation. Students are called to be "the more," to be agents of transformation and to be "founders" in a world broken and longing for unity and reconciliation. The philosophy advances holistic development with an emphasis on global justice and responsibility in an atmosphere that fosters excellence tempered by gentleness and compassion. Mount Saint Joseph Academy remains faithful to "educating founders" and to the belief that "on the education of women largely depends the future of society."
