Ron Nierenhausen, the Elk River Police Department’s new patrol captain, took the oath of office this week.

He was sworn in by Mayor John Dietz during the Tuesday, Jan. 18 Elk River City Council meeting.

Nierenhausen replaces Brad Rolfe as patrol captain. Rolfe was named Elk River police chief following the recent retirement of Police Chief Jeff Beahen.

Nierenhausen is a 22-year veteran of the Elk River Police Department. He was hired as a police officer in 1988 and promoted to sergeant in 1996.

He has a bachelor’s degree from St. Cloud State University, a master’s degree from Concordia University and is a graduate of the Northwestern University School of Police and Command.
The patrol captain supervises the police department’s patrol division consisting of four sergeants and 17 patrol officers.
