2 Health Care Giants - HealthPartners, Park Nicollet - Plan to Merge

Two of the Twin Cities' most prominent health care systems, HealthPartners and Park Nicollet, have signed an agreement to join operations, marking the biggest merger in the local health care market in two decades.

If approved by state and federal regulators, the merger would create the state's second-largest hospital system by revenue, behind the Mayo Clinic in Rochester, and combine two organizations with storied traditions in Twin Cities medical care.
