St. Joseph's Indian School is a Native American school dedicated to improving the quality of life for Lakota (Sioux) children and families. As an apostolate of the Congregation of the Priests of the Sacred Heart, St. Joseph’s mission is to educate Native American children and their families for life — mind, body, heart and spirit. This mission drives our organization to educate and provide housing for approximately 200 Lakota (Sioux) children each year.
