William E. Lewis, Assistant Director, Audits and Investigations

William E. Lewis is currently the Assistant Director, Audits and Investigation where he directs and oversees the work of 65 auditors and seven administrative investigators. To this position he brings an array of knowledge and experiences acquired over his 25 year career in service to the State of California.

Mr. Lewis began his state career working for three years at the State Auditor’s Office. Impressed with the level of professionalism he observed when interacting with counterparts at Caltrans, he accepted a position within the Caltrans Division of Accounting (DofA), where he would spend the next 20 years rising through the ranks to the level of Office Chief, Office of Accounts Receivable, Systems and Administration. Always driven to innovate and improve systems, Mr. Lewis had many successes during his tenure with DofA, including the development and implementation of an electronic payment system for contractors, resulting in significant cost and time savings to both parties.

Mr. Lewis attended the University of Utah, where in 1988 he earned a Bachelor of Arts degree in Accounting. In 1991, he received a license to practice as a Certified Public Accountant, which he maintains to this day. The second oldest of six children, William grew up in Northern California, where he now lives and cultivates strong ties to the region. An avid runner, cyclist, outdoorsman, and youth soccer coach, Mr. Lewis is highly active both physically and with the community he serves. He dedicates most of his time away from work to his wife of 34 years, five children, and 11 grandchildren.
