In memory of our founder
Charles F. “Buddy” Turner Sr., R.N.
March 26, 1939 – November 10, 2025
Founder, President and CEO
North Greenville Fitness exists because of Buddy Turner. A Furman University graduate and U.S. Army veteran who served as a tank commander in West Germany and left the service as a Captain, he spent years in sales and business before going back to school to become a Registered Nurse, with a specialization in cardiac care.
A devoted runner and cyclist for more than forty years, he founded this clinic in Travelers Rest and led it until the day he died. Along the way he personally monitored the testing of tens of thousands of firefighters and first responders and performed more than 85,000 stress tests, usually while giving whoever was on the bike a good-natured hard time.
Serving firefighters and first responders was his life’s mission, and he cared about every person who worked with him and every person who came through his clinic.
The company he built carries on his mission. We honor his legacy with every screening.
