Darin Atteberry

City Manager

Hello, and welcome to the Fort Collins City Manager's Office. Here at the City of Fort Collins we are passionate about creating a vibrant, world-class community. Approximately 1,200 full-time employees, and up to 1,000 additional seasonal employees, work diligently to provide exceptional service to our residents and visitors.

The City of Fort Collins operates within a council-manager form of government, which means that the City Manager is the chief executive officer of the City and is responsible for the overall management of City operations. The City Manager works in close partnership with the Mayor and City Council, who are responsible for setting the policy direction of the City.

On, you will find a wealth of information about our City and the services we provide. I always like to hear from you, so please feel free to e-mail me with any comments or suggestions.
