In a series of promotions made by Ozaukee County Sheriff Jim Johnson, Operations Capt. Christy Knowles has been promoted to undersheriff, the first woman to be named the department’s second in command.

Knowles replaces Undersheriff Jeff Taylor, who officially retires March 15.  

Lt. Marshall Hermann is being promoted to operations captain, succeeding Knowles, and Det. DeMaine Milbach succeeds Hermann as lieutenant.

Knowles was hired in October 1999 as a jail deputy and was promoted to patrol officer in September 2001. In August 2007 she was promoted to the Detective Bureau. While in the bureau her main assignment was investigating sensitive crimes. 

In January 2012 she was promoted to lieutenant and commander of the patrol division. In January 2015 she became the department’s first female captain and in charge of operations.

Taylor joined the Ozaukee County Sheriff’s Office in February 1991 as a jail deputy. He was promoted to patrol officer in December 1992 and in May 1995 he was promoted to detective, spending the majority of his time as the lead drug detective. He was promoted to lieutenant in June 2009, to operations captain in January 2012 and to undersheriff in January 2015. 

Undersheriff can act on behalf of the Sheriff’s Office and manages the other command staff. The operations captain oversees the patrol and investigative divisions of the department.
