Bob Grogan, C.P.A.
County Auditor
As the County's only independently elected officer responsible for evaluating and reporting on County operations, the County Auditor conducts internal audits of the operating departments, systems and internal controls in County government. The Auditor evaluates how County resources/assets are protected, used and recorded; how and where County money is spent; and how County departments are operating. The Auditor prepares recommendations for improving systems and processes.
The County Auditor receives information regarding observations of waste, fraud and misuse of resources related to County operations and programs. Audit procedures are performed relative to these allegations. When deemed appropriate, the results of such audit procedures are presented to the State's Attorney for further investigation.
The Auditor is responsible for auditing vouchers to be paid by the County Board and recommending their payment or rejection. The Auditor reports quarterly on the entire financial operations of the County, including revenues, expenditures, encumbrances, and changes in fund balance for the County's operating funds. The Quarterly Financial Reports are available on this website. In addition, the Auditor has prepared a brief brochure to aid in understanding the contents of the Quarterly Financial Reports.
County Auditor Bob Grogan is a strong advocate of transparency in government. Accordingly, the Auditor's Office provides detailed expenditure reports listing County payments on a monthly basis. This provides timely and pertinent information about County operations to the citizens and taxpayers of DuPage County.
