About OEM

The Office of Emergency Management was commissioned on January 1, 2015, drawing together disparate operations from Milwaukee County’s Department of Health & Human Services, Office of the Sheriff and Information Management Services Department. County Executive Chris Abele appointed Christine Westrich as founding director of OEM; the Milwaukee County Board of Supervisors confirmed her appointment on February 5, 2015.
