About Us

Meet Our Team

Every patient is under the care of a radiation oncologist who is a cancer specialist with expertise in the application of radiation therapy as it is used in the management of cancer. In a large program such as ours, the radiation oncologists have particular expertise with specific types of cancer. This ensures that your physician is one who focuses on your specific type of cancer.

In the Department of Radiation Oncology, our goal is to develop and implement treatment programs geared towards maximizing the chances of cure while minimizing the radiation dose to normal organs, thus attempting to maintain your quality of life and preserve your normal organ function. Our radiation oncologists maintain strong academic, clinical and research interests, and a commitment to your well being. In addition, many on our staff are faculty members of the James H. Quillen College of Medicine, our local medical school.
