Millions of Wisconsin residents will be affected by two separate mergers of nonprofit hospital systems that were finalized earlier this month.
Gundersen Health System and Bellin Health completed a merger on Dec. 1. The next day, Advocate Aurora Health and Atrium Health did the same. Together, the mergers will impact about 8.5 million patients across several states.
Bellin and Gundersen will keep their respective names for the time being, as well as separate headquarters in Green Bay and La Crosse, while Advocate Aurora and Atrium will become “Advocate Health.” Marshfield Clinic Health System and Essentia health also announced merger talks earlier this year.
