About Us

Our patients have access to the highest standard of care by highly experienced radiation oncologists who employ a range of advanced techniques and technologies. Radiation oncologists at this practice location offer consultations about radiation therapy for patients who have a new cancer diagnosis. We work as part of a greater multidisciplinary team at Wellstar North Fulton Hospital for patients with all types of cancer, including breast cancer, prostate cancer, lung cancer and brain and spine cancer. This is because we believe in doing what’s best for the patient.

Advanced technology & techniques

Our radiation oncologists perform intraoperative radiation therapy (IORT) in tandem with a breast surgeon at Wellstar North Fulton Hospital. A surgeon removes the tumor and a radiation oncologist directly applies radiation while the patient is asleep in the operating room. We also offer radioactive seed implant for prostate cancer patients.

For patients who require other types of radiation, our network of Wellstar cancer care locations deliver a wide variety of treatment options with state-of-the-art technology including HDR, CyberKnife, TrueBeam and TomoTherapy.
