St. Joseph's Academy is a private, all-girls, Roman Catholic, college preparatory high school in Frontenac, Missouri, a suburb of St. Louis. It is located in the Roman Catholic Archdiocese of Saint Louis.HistorySt. Joseph's Academy was founded as Mother Celestine's in 1840. Mother St. John Fontbonne and the Superior Sisters of St. Joseph were sent from Lyon, France to the territories of Cahokia and Carondelet. Upon their arrival, they opened a convent school. Following this, they founded the St. Joseph Institute for the Deaf in 1937. In 1841, Mother Celestine's moved from the log cabin that it had been founded in to a motherhouse in Carondelet, Missouri. In 1925, the Academy moved into Clayton, Missouri along with Fontbonne University. In 1946, the campus became too small for both the high school and the college, so the Academy decided to move to Frontenac, Missouri, its current location. In 1955, the new school opened.Notable alumni Kristin Folkl, professional basketball player Tisha Terrasini Banker, actress Molly McNearney, co-head writer of Jimmy Kimmel and wife of Jimmy Kimmel
