St. Francis de Sales is Chicago's oldest coeducational Catholic high school. Located in Chicago East Side neighborhood, the mission of St. Francis de Sales is to build a Catholic educational community that allows for the uniqueness of each student, while fostering charity, tolerance and understanding through academic, social and spiritual development. We believe that every St. Francis de Sales student deserves an education that is centered around academic excellence in an environment that embraces social, economic, cultural and religious diversity.
