Internal Auditing is an independent, objective assurance and consulting activity designed to add value and improve an organization’s operations. The function helps an organization to accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control and governance practices.


Internal Audit’s mission is to serve the citizens of Guilford County by providing consulting and audit services that help county government reduce risk with proper internal controls and promote accountability through efficient and effective use of resources.


The Internal Audit Department reports directly to the County Manager. This enhances the department’s ability to operate independently and without bias in regard to County activities. The department conducts its work in accordance with the International Standards for the Professional Practice of Internal Auditing, a part of the Professional Practices Framework promulgated by the Institute of Internal Auditors.


The Internal Audit Department consists of one director and three full-time auditors. Staff members have an average of 20 years’ experience in auditing and accounting in the public and private sectors. Experience includes banking, manufacturing, healthcare and local government auditing and accounting. Staff members have Bachelor’s Degrees in Accounting, Business, Finance and Political Science; Master’s Degrees in Business Administration and Public Administration; and a PhD in Public Administration. Professional certifications of staff members include Certified Public Accountant (CPA), Certified Internal Auditor (CIA) and Certified Internal Control Specialist (CICS).
