E. Thomas Chaney, former executive of Hospital Affiliates, Inc. and David Steffy and Richard Ragsdale, former executives at Hospital Corporation of America spinoff Republic Health Corporation, formed Community Health Systems in 1985.
In 2007, Community Health Systems purchased Plano, Texas-based Triad Hospitals for $6.8 billion, adding nearly 50 hospitals, hospital management and consulting business Quorum Health Resources, and nearly doubling the size of the company. Among the facilities included in the deal was McKenzie-Willamette Hospital in Springfield, Oregon; Trinity Medical Center in Birmingham, Alabama; and the seven hospitals of Lutheran Health Network in the Ft. Wayne, Indiana region.
In 2013, Community Health Systems entered into an agreement with Health Management Associates to purchase HMA for about $3.6 billion in cash and stock. The merger was completed in January 2014 and made Community Health Systems the largest for-profit hospital operator at the time, with 206 hospitals in 29 states.
