History

In 2016, the health system announced plans for a $500 million renovation at MercyOne Des Moines Medical Center in downtown Des Moines. The project is expected to take five to eight years and include a new 11-story hospital tower as well as power plant.67

Bob Ritz was appointed company president and CEO, effective July 1, 2017.8

In 2019, the company changed its name from Mercy Health Network to MercyOne, and rebranded its 450 locations.9

In 2020, an employee improperly accessed patient information; the data breach resulted in a class-action lawsuit settled by the company in 2024 for $1.8 million.1011

Trinity Health acquired CommonSpirit Health's 50% stake in MercyOne in September 2022.4

MercyOne merged with Genesis Health System in March 2023.1213

In 2024, the MercyOne health network comprises over 40 hospitals and more than 230 health care facilities.1
