About Sioux Rivers

Sioux  Rivers Regional MHDS


On July 1, 2014 the Sioux Rivers Region was formed with the vision of creating a service system that makes funding and service availability more equitable across county lines.  The Sioux Rivers Regional Management Plan is designed to provide access, information, and coordination of funding, while providing for the health, hope, and successful outcomes of the adults in our region who have mental health and intellectual/developmental disabilities, including those with multi-occurring substance use issues, health issues, physical disabilities, and other complex human service needs.


In accordance with the principals enumerated in legislative redesign of the mental health delivery system, Sioux Rivers MHDS works in a quality improvement partnership with stakeholders in the region (providers, families, individuals, and partner health and human service systems) to develop a system of care approach that is characterized by the following principles and values:



Welcoming and individualized


Person and family driven


Recovery focused




Service to individuals with multiple diagnoses
