Our Physicians

Sure, they can tout their credentials, but they’d rather talk about results.

The physicians at Radiotherapy Clinics of Georgia (RCOG) are some of the finest, most experienced radiation oncologists in the United States. Though their backgrounds differ, each has come here because they believe that data-driven, evidence-based medicine can save more lives. In addition to being talented practitioners, our physicians are actively involved in the advancement of cancer research. In fact, RCOG is responsible for more published papers on prostate cancer than any other radiation practice in Georgia.
