The Fort Dodge Fire Department will assume responsibility for the ambulance service now provided by UnityPoint Health — Trinity Regional Medical Center in a transition that hospital and city officials say will provide outstanding care in a financially sustainable way. The change will become effective July 1, city and hospital leaders announced Monday. “This new structure will ensure a more sustainable model for both entities while continuing the strong collaboration in delivering high-quality emergency medical service to the community,” Fire Chief Steve Hergenreter said. The Fire Department ambulances will serve Fort Dodge and all of the surrounding areas including Barnum, Coalville, Moorland and Otho.
