Brentwood Police Chief Thomas Hansen is planning to retire next month after a 35-year career in law enforcement, he announced this week.

The Police Department will soon initiate an internal recruitment to find a new chief before Hansen’s last day on Sept. 30.

Over the course of 27 years in Brentwood, Hansen worked his way through the ranks as an officer, sergeant, lieutenant and captain before he was promoted to police chief in 2017.

As chief, Hansen added 12 positions to the police force, initiated a community policing branch and kickstarted a Naloxone program, so officers can step in if a community member overdoses on opioids. He also worked as an acting assistant city manager in City Hall in 2021.

City Manager Tim Ogden said he views Hansen as a friend more than a work colleague.

“Tom has redefined the industry standard for police chiefs with his passion and love for law enforcement, his tireless dedication to serving everyone in the community and unparalleled expertise in leading one of the finest police departments,” Ogden said in a statement. “He will be missed, but we’re excited for him to enjoy this next phase of his life with his family.”

Hansen said he’s “incredibly proud” of the Brentwood police force for working together to mitigate the challenges that law enforcement faced over the past few years.

“I want to thank the community of Brentwood for putting their trust in me to serve as your police chief; I hope I exceeded your expectations,” Hansen said in a statement. “I have lived the majority of my adult life as a police officer, and as I return to civilian life, Brentwood will never be far from my heart!”

A transfer of command ceremony is planned for Sept. 28, the department said.
