Mercy

Mercy is a non-profit Catholic healthcare organization founded in 1871 by the Sisters of Mercy. Headquartered in Chesterfield, Missouri, within Greater St. Louis, its core mission is to extend the healing ministry of Jesus by improving community health, with a particular focus on serving the poor and underserved.

The organization operates as the seventh largest Catholic health care system in the United States, encompassing more than 40 acute care and specialty hospitals, alongside over 700 physician and outpatient clinics. Mercy provides a comprehensive range of healthcare services, including primary care, specialty care, emergency services, urgent care, and various medical specialties such as cardiology, oncology, orthopedics, women's health, and behavioral health. Its services primarily extend across Missouri, Arkansas, Oklahoma, and Kansas, with additional ministry outreach programs in Texas, Louisiana, and Mississippi.

As of April 1, 2022, Steve Mackin serves as Mercy's CEO. The organization employs over 40,000 workers and more than 2,400 physicians. Recent notable developments include being awarded funding in April 2026 to enhance care for patients with chronic high blood pressure, and its CEO being recognized on a list of Great Leaders in Healthcare. Additionally, in April 2026, Newsweek ranked Mercy Birth Centers among America's Best Maternity Hospitals.
