Denver Mayor Mike Johnston has made his selections for a deputy mayor and legislative director.

Adrina Gibson, who was appointed by Johnston in August 2025 to lead the Department of General Services, was selected to be the city’s deputy mayor on Monday, according to a news release from the mayor’s office. She will continue to serve as the executive director of General Services, and will step in to take over mayoral duties whenever Johnston is unable to do so.

Gibson initially joined General Services in 2024 as the department’s deputy executive director.

She will take over the deputy mayor role from Al Gardner, who has served as deputy mayor since January 2025. Gardner has since been named executive director over public safety, overseeing Denver’s police, fire and sheriff’s offices.

Gibson has worked for the City and County of Denver since February 2019, according to her LinkedIn page. She first served as chief officer of the division of small business opportunity before joining the general services department. Prior to that, she worked for the Regional Transportation District as manager of the small business office.

“Adrina is a dynamic leader whose dedication to innovation, equity, and operational excellence continues to strengthen services Denver residents rely on every day,” Johnston said in the news release. “I am deeply grateful to Adrina for stepping into the role of Deputy Mayor, and look forward to working closely together to serve Denver with dedication and purpose.”

As for the legislative director role, Johnston selected Tim Hoffman — a former prosecutor in the Denver District Attorney’s office. In the role, Hoffman will oversee legislative efforts for the mayor’s office, which includes working with the City Council and ensuring Johnston’s initiatives are implemented.

In addition to his six years as a prosecutor, Hoffman spent time as an assistant United States attorney in the U.S. Attorney’s Office for the District of Colorado, and interned at the White House. He ran for Denver City Council in 2023, and has worked in the mayor’s office for the past two and a half years, serving as a deputy legislative director and director of policy.

“Tim is an incredible public servant with a proven track record of building positive relationships and successfully navigating the minutiae of Denver’s municipal code,” Johnston said in the news release. “I look forward to continuing to work shoulder-to-shoulder to deliver on our promise of a vibrant Denver.”
