Mundelein police Cmdr. Don Hansen has been named the department's newest deputy chief.
Hansen's promotion comes a few months after Eric Guenther rose from deputy chief to chief. Guenther replaced longtime Chief Raymond J. Rose as the town's top cop.
Hansen was unavailable for comment Friday.
Hansen will be feted by the village board during its meeting Monday night at the town's main fire station.
The promotion was effective in mid-May, but it wasn't announced to the public until this week.
Hansen joined the Mundelein Police Department as a patrol officer in 1989. After two years on patrol, he moved to investigations and served there for nine years.
In later years, he was promoted to sergeant and then to commander in 2006.
Hansen also served as a member of the Lake County Major Crimes Task Force for six years, among other duties.
The department typically has two deputy chiefs. John Monahan has been the other deputy chief since 2011.
Before the village board congratulates Hansen on his promotion Monday, it will recognize police officer Scott Clark as the department's 2012 employee of the year.
Clark is the town's code enforcement officer. According to a memo from Guenther, Clark is being recognized for assisting an elderly homeless person and for helping to force the owner of a dilapidated property to improve the building, among other accomplishments.
Clark joined the department in 2002 as a patrol officer. He was assigned to code enforcement after seven years on patrol.
