The agency Director's Office directs and coordinates certain executive administrative functions including media relations, community relations, and legal and legislative affairs. An administrative services division provides centralized support for the agency. ADEQ also maintains regional offices in Flagstaff and Tucson, with community liaisons posted in the four corners of the state, to better serve our customers.
