About Us
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. Wellstar radiation oncologists work as part of a greater multidisciplinary team including medical oncologists, surgical oncologists and surgeons in many specialties, genetic specialists and more. A nurse navigator is here to walk patients through each step of the process. Nutritional counseling, care coordination and support groups are also available to patients. We believe in doing what’s best for the patient. 

Highest standard of care

Additionally, our team is highly experienced. Patients with cancer can have better outcomes when they are treated by radiation oncologists with depth of experience.

Advanced radiation therapy

Wellstar Paulding Radiation Oncology is proud to offer patients world-class care, close to home. Our patients have access to advanced techniques and technology in radiation therapy treatment such as Intensity modulated radiation therapy (IMRT). IMRT allows the radiation oncologist to precisely control the intensity of the radiation that different parts of a tumor receive. Our radiation oncologists use advanced imaging capabilities such as Image Guided Radiation Therapist (IGRT) that allows verification of the patient position and tumor position at the time of treatment. Other techniques include high-dose-rate brachytherapy (HDR), volumetric-modulated arc therapy (VMAT) and accelerated partial breast irradiation (APBI). Breast patients who are candidates for APBI treatments complete treatments in five days.
