John Warner Ray, M.D., FACRO

Medical Director, Radiation Oncology Services, Inc.

A native of Atlanta, Dr. Ray graduated from Emory University Medical School in 1966 and completed his internship and a year of medical residency at Wilford Hall United States Air Force Hospital in San Antonio, Texas. Subsequently, he served in the United States Air Force as a Flight Medical Officer prior to entering his residency in Radiation Oncology at the University of California, San Francisco. Dr. Ray obtained board certification in 1975 and returned to Atlanta as Director of Radiation Oncology at South Fulton Medical Center. At South Fulton, he developed a keen interest in community based radiation oncology programs that would blend the highly technical aspects of radiation therapy with compassionate care in a comfortable setting.

In 1983, Dr. Ray developed the first freestanding radiation therapy center in Georgia. Today, the center is still located in Riverdale adjacent to Southern Regional Medical Center. Over the years, Dr. Ray has developed radiation therapy centers in the communities of Austell, East Point, Newnan and Griffin. Each center has received praise from patients and physicians for providing state-of-the-art treatment in a warm, community setting.

As founder and Medical Director of Radiation Oncology Services (ROS), Dr. Ray provides leadership for program development at all ROS centers. In 1995, Dr. Ray had a vision for the company that included Joint Commission accreditation. The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) sets the standard for quality care in hospitals and outpatient facilities. ROS, under the leadership of Dr. Ray, voluntarily sought and received full accreditation after an intense review process. Since the first accreditation, ROS has successfully maintained JCAHO approval by undergoing a stringent review process every three years. Strict adherence to JCAHO quality guidelines is one of the many examples of ROS’ commitment to the highest quality of care standards.

Dr. Ray has developed a variety of clinical cancer treatment programs for numerous Atlanta area hospitals. Through his many efforts, ROS and the affiliated hospitals currently have active prostate seed implant programs as well as high dose rate brachytherapy programs for the treatment of gynecological cancers. Dr. Ray was also instrumental in establishing an active partial breast radiation therapy program for breast cancer patients.

Of all the many programs he has implemented over the years, Dr. Ray is most proud of the ROS program known as Evidence Based Peer Review. Every week for the past 20 years, ROS physicians meet to discuss all new patients referred for radiation therapy. The conference provides a forum for group discussion, peer review and consensus as to how best treat a particular patient. Most importantly, the conference ensures that all patients receive individualized treatment consistent with both ROS and national standards of care.

As the senior physician member of a staff of 10 board-certified radiation oncologists, medical physicists/dosimetrists and a large support staff, Dr. Ray continues his very active role in ROS. His leadership and oversight allows ROS to continue in its efforts to blend the very technical aspects of radiation therapy with the compassionate care needed for each ROS patient and family.
