Three veteran Knoxville Police Department officers have been promoted to advanced supervisory ranks.

Sgt. Michael Dabbelt has been promoted to Lieutenant, while Officers Tim Campbell and Robert Cook have been promoted to Sergeant. Those three have accumulated over 40 years of combined law enforcement experience.

Dabbelt joined the KPD in 2009 and was promoted to Sergeant in 2020. He has spent the majority of his time at the KPD on patrol and most recently served as an investigator within the Office of Professional Standards.

Campbell has served the KPD since 2011. A member of the department’s Special Operations Squad, Campbell has spent the entirety of his career on patrol. Most recently, he served on the Co-Responder Unit, working alongside a behavioral health clinician to respond to calls involving individuals in crisis.

Cook joined the KPD in 2008, spending the early part of his career on patrol. In 2013, he became a detective in the Special Crimes Unit before transferring to the Violent Crimes Unit in 2015. He served in that role until 2022. Most recently, he supported the department’s hiring efforts as the internal background investigator.

“I am excited to promote Michael, Tim and Robert to new supervisory positions,” Chief Paul Noel said. “These three have displayed a commitment to our organizational mission and values and are ready to take on greater responsibility. I am confident they will excel in their new roles and help propel our department forward.”

All three will be assigned to Field Operations squads. The promotions took effect on Sunday, August 24.
