The mayor of North Mankato has announced he’s running for the Nicollet County Board of Commissioners. Mark Dehen made the announcement Wednesday afternoon. In a statement, Dehen said he looked forward to continuing to be a strong advocate for the citizens of North Mankato at the county level. He said it is bittersweet as he reflects on his work for the city of North Mankato for the past 11 years, but the city is in a solid position financially with a strong council, an excellent administrator and staff and with a robust strategic and long-range plan in place for the future.
