Achievements of Shannon Teresi

Shannon Teresi McHenry County Auditor

History and Professional Experience

Shannon Teresi worked as an audit and tax professional for PricewaterhouseCoopers, Big 4 accounting firm where she obtained professional auditing and financial experience at a top firm in Chicago.

In 2010, Shannon Teresi worked for the McHenry County Auditor's Office in 2010 as their Internal Auditor and moved into the Financial Reporting Manager/Chief Deputy position. In that role, her main duty was to prepare the County's financial statements and government accounting.

County Auditor Accomplishments

Shannon Teresi implemented a paperless/electronic bill approval process Countywide, which saves staff time through out all departments.  Instead of County staff in each department moving the hard copy invoices throughout the departments and then to the Auditor's Office for approval; approval is obtained electronically by the department head and then routed to the Auditor's Office for approval. 

Shannon Teresi implemented a requisition and purchase order approval process by the Auditor's Office to comply with the Auditor statute.  Taxpayer dollars are saved daily because Auditor's Office verifies every purchase request services a public purpose and has board approval.  It stops wasteful purchases that don't benefit McHenry County.

Shannon implemented a department head and Auditor's Office review over wire transfers to ensure payments are authorized and have adequate support.
