Concordia University Chicago is an American private, Lutheran liberal arts university located in the Illinois suburb of River Forest, 10 miles west of Chicago. Concordia serves over one thousand undergraduates and three thousand graduate students through its four colleges: The College of Arts and Sciences, College of Education, and College of Business, and College of Graduate and Innovative Programs. Many of these attend classes at sites around the Chicago metropolitan area, rather than on its River Forest campus. Concordia is a member of the Concordia University System, a network of ten American colleges and universities affiliated with the Lutheran Church - Missouri Synod. Concordia's athletic teams are called the Cougars. They compete in the NCAA Division III. The school colors are maroon and gold. In 1855, Lutheran ministers Friedrich Johann Carl Lochner and Philipp Fleischmann established a private "teachers' seminary" in Milwaukee, Wisconsin to train day school teachers for Lutheran schools. In 1857, responsibility for the operation of the school was taken over by the Lutheran Church - Missouri Synod.
