The American Civil Liberties Union of Indiana is looking for a new executive director.
Gilbert Holmes will retire March 31 after three years of leading the civil rights group.
The ACLU says its board of directors will name an interim director and conduct a national search for Holmes' replacement.
Before joining the ACLU in December 2008, Holmes had served as president and CEO of the IndyGo bus line in Indianapolis and commissioner of the Indiana Bureau of Motor Vehicles. He also held executive positions at Lincoln National Corp. in Fort Wayne, Methodist Hospital in Indianapolis and the Indianapolis Museum of Art.
The ACLU of Indiana is the Indiana affiliate of the American Civil Liberties Union.
