Southern Crescent Radiation Oncology Center

ROS – Riverdale is proud to have served the community since 1983.  In our 2014 affiliation with Piedmont Healthcare, our name changed to Southern Crescent Radiation Oncology Center.  Despite a name change, the center is still home to the same physicians, staff and programs.  Medical Director, John Giesler, M.D., and colleague, Sasha Wahab, M.D., continue to direct the clinical activities of the center
