The Department of Public Safety (DOS) unifies all the city agencies tasked with ensuring Denver is the safest and most welcoming city in the nation. Our mission is to deliver a full spectrum of high-quality public safety services to individuals who live, work and visit the City and County of Denver.

Under the guidance of the Executive Director, who is appointed by the city's mayor, DOS provides management, discipline, human resources, administrative support and policy direction for Police, Fire and Sheriff Departments,  the 9-1-1 Combined Communications Center, Public Safety Youth Programs, Community Corrections and the Gang Reduction Initiative (GRID). The DOS also oversees the Public Safety Cadet Program, a program for high-performing high school graduates who are interested in becoming a police officer, firefighter or deputy sheriff in Denver.

The Executive Director is the highest authority in the Department of Public Safety and provides oversight, leadership and guidance to the each of the divisions through their leadership teams. In addition, the Executive Director's office is responsible for issuing fair and unbiased discipline decisions on behalf of Police, Fire and Sheriff Departments.
