The Arizona Association of Counties (AACo) is the only state organization that represents all of the county officials and the governments they serve in the State of Arizona. Founded in 1968, AACo provides essential services to the state's counties.
AACo advances issues with the state and federal government, improves the public understanding of county government, assists counties in finding and sharing innovative solutions through education and research, and provides value-added services to save counties and taxpayers money.
Members may reserve meeting space for county meetings and functions. Additionally, working office space is available for members who need a quiet place to work while in Phoenix.
To make reservations or inquire about availability, please contact our office by calling (602) 252-6563 ext. 221. AACo is conveniently located across the street from the Arizona Capitol in Phoenix, Arizona.
