History of the County Auditor

The Office of the County Auditor was established by an act of the Illinois General Assembly in 1911, and except for Cook County, Illinois' largest counties have an elected County Auditor. The County Auditor is elected for a 4-year term, in the same general election as the President of the United States. DuPage County elected its first County Auditor in 1932, when the county's population reached 75,000. Since then, six persons have served as County Auditor. The current County Auditor, Bob Grogan, has held the office since December 1, 2008.
