Denver has an independently-elected Auditor to serve as a check and balance on Denver’s “strong mayor” form of government. Timothy M. O’Brien, CPA, was elected to a four-year term as Denver’s 24th Auditor in 2015 and re-elected in 2019 and 2023. The Auditor’s Office is responsible for internal audit services and civil wage theft, minimum wage, and prevailing wage enforcement. Read our 2025-2026 Strategic Plan(PDF, 5MB).
