Founded in 1890 by the Sisters of the Congregation of St. Joseph with the mission to foster unifying relationships with God and all creation, Saint Joseph Academy is the only all-girls Catholic high school in the city of Cleveland. Committed to Catholic values and academic excellence in grades 9 through 12, we educate young women of diverse cultures, abilities and backgrounds, empowering them to be successful, compassionate leaders in the 21st-century global society.
