Michael C. Riordan is President and CEO of Greenville Hospital System University Medical Center (GHS), one of the largest not-for-profit healthcare providers in the Southeast. The 1,268-bed system, which has anticipated operating revenues of approximately $1.4 billion in fiscal year 2010, is home to 14 medical residency and fellowship programs, South Carolina’s first patient simulation center and nearly 600 active clinical research trials. GHS provides patients a sophisticated network of expertise and technologies through its tertiary medical center, research and education facilities, community hospitals, wellness centers, physician practices (University Medical Group) and numerous specialty facilities in upstate South Carolina. In 2008, GHS provided $223 million in quantifiable benefits to its surrounding communities.
Riordan began his duties at GHS in August 2006. From 2001 to mid-2006, he led the University of Chicago Hospitals and Health System.

Under his leadership, GHS has collaborated with community groups to make possible innovative initiatives such as a rails-to-trails corridor called the Swamp Rabbit Tram Trail and other healthier-living catalysts such as an expanded Activate Upstate and a low-cost wellness partnership with the YMCA of Greenville for patients at risk for chronic disease. This is a program of PATH – Partners Achieving Total Health. GHS has also launched a program to help local businesses improve employee health while still curtailing company heath costs.
