We wanted to reassure you that Arizona Oncology remains open to provide medically necessary, life-sustaining care. In addition, our expert care team can now see patients through scheduled virtual appointments on a secure platform from the comfort and safety of your home.

Updated visitor policy: For the safety of our patients and staff, no visitors will be permitted into the clinic. Family members and caretakers may participate in the appointments remotely by phone or video conference if desired. All patients and staff will be required to wear a face covering(or mask) that covers the nose and mouth. This new policy reflects the recent recommendations by the CDC to reduce community-based transmission.

If you have flu-like symptoms, you should contact Arizona Oncology before visiting our clinics for scheduled appointments. This includes fever and symptoms of respiratory illness, such as coughing or difficulty breathing.

We ask that you follow our tips to stay healthy and to help do our part in prevention of spreading of these viruses.

Dr. Frye specializes in radiation oncology with expertise in treating brain and spine tumors, as well as lung, gastrointestinal, and head and neck malignancies.

While studying for his undergraduate degree, he participated in a research fellowship at The University of Florence, Italy in neuropharmacology. He received his medical degree from Dartmouth Medical School.

Dr. Frye completed residency in the Department of Radiation Medicine at Georgetown University Hospital where he received specialized training in stereotactic radiosurgery and stereotactic body radiation therapy. He was also trained in using unsealed radiation sources. Following his residency,
Dr. Frye was an attending radiation oncologist for the Duluth Clinic in Duluth, MN, where he served as the section chair and medical director of the region’s first stereotactic radiosurgery program. He was then recruited to Georgetown University Hospital, where he served as a clinical instructor.

Currently, Dr. Frye serves as Division Chief of Neuro-oncology at the Carondelet Neurological Institute. He is an active member of the American Society of Radiation Oncology.

He believes in patient-centered care, including a commitment to multidisciplinary collaboration with each patient’s clinical team, which can be comprised of additional physicians, nurses, radiologic technicians and medical physicists. This team approach is enhanced by thorough ommunication with his patients, their families, and the clinical care providers. He practices goal-oriented care, maximizing treatment results and minimizing side effects, with an aggressive approach to pain management.





In addition to his clinical work, Dr. Frye enjoys cycling, running, skiing, and traveling.
