Interim CEO
Marshfield Clinic Health System | Marshfield
Emergency medicine specialist Dr. Brian Hoerneman has served as interim chief executive officer of Marshfield Clinic Health System since September 2023, following the departure of former CEO, Dr. Susan Turney.
Marshfield Clinic operates more than 60 clinic sites, 11 hospitals, a children’s hospital, a research institute and the Marshfield Clinic Health System Foundation. It has more than 1,400 providers across Wisconsin and Michigan’s Upper Peninsula.
Under his leadership, the health system has pursued a merger with Sioux Falls, South Dakota-based Sanford Health, a deal that is expected to close by the end of 2024. When combined, they will form a 56-hospital, $10 billion health system with nearly 56,000 employees. Under the deal, Sanford Health will become the parent company, with Marshfield Clinic becoming a region within Sanford Health. Hoerneman would serve as president and CEO of the Marshfield Clinic Health System region.
Earlier, Marshfield Clinic explored a merger with Essentia Health but called off those talks in January 2024.
