The president of Columbia College will be retiring this year. Dr. Gerald T. Brouder made the announcement yesterday after almost 18 years as the leader of the college which has a campus in Lake Ozark. His last day will be August 1st. Before coming to Columbia College in 1995, Brouder spent 17 years at the University of Missouri where he served as provost and interim chancellor. A search committee will soon be put together to find the 17th president of Columbia College.
