Leadership change announced for Mercy’s St. Louis operations
Mercy has appointed Tricia McGusty as president of Mercy St. Louis Communities, a role that includes oversight of Mercy Hospital St. Louis, the health system’s largest hospital. The appointment was announced Monday, March 9, 2026, and Mercy said McGusty began in the position the same day following a nationwide search.
The St. Louis Communities portfolio includes Mercy Hospital St. Louis and related regional operations. Mercy is headquartered in the St. Louis area and operates hospitals, clinics and outpatient facilities across multiple Midwestern and Southern states.
Incoming president’s background and recent role
Mercy said McGusty brings more than 25 years of health care experience, including about 15 years in leadership roles at large hospitals. Immediately before joining Mercy, she served as chief operating officer at HCA Houston Healthcare Northwest and also worked as interim chief executive officer during an executive transition, with responsibilities that included maintaining operational performance and continuity of strategy and physician engagement.
Mercy stated that McGusty has experience leading major hospital construction projects, a background the system described as relevant to current plans to update facilities and expand access to care in the St. Louis region.
Facility renovation cited as early priority
One of McGusty’s initial assignments will be to oversee a large campus renovation at Mercy Hospital St. Louis, Mercy said. The system characterized the renovation as part of broader investment in facilities and access to care locally, though specific timelines, costs and construction scope were not detailed in the announcement.

Transition plan for outgoing president
Mercy said Dr. David Meiners, who has served as president since 2020, helped recruit McGusty and will remain in place during the transition period. After that, Mercy said he will move into an executive advisor role, continuing to provide leadership and clinical expertise.
Mercy said the transition is designed to provide continuity in leadership as the organization moves forward with facility investment and regional access initiatives.
Mercy’s broader footprint
Mercy describes itself as a highly integrated health care system spanning Arkansas, Illinois, Kansas, Missouri and Oklahoma, with additional clinics, outpatient services and outreach ministries in Arkansas, Louisiana, Mississippi and Texas. The system reports operating dozens of acute-care and specialty hospitals, a large network of outpatient locations, and a sizable physician and advanced-practitioner workforce.
In its announcement, Mercy also reported that in fiscal year 2025 it provided more than half a billion dollars in free care and other community benefits, including traditional charity care and unreimbursed Medicaid.
