Clinical Interests
I am interested in providing holistic care for our patients and their families. I strive to listen and inform so my patients can make the decision and steer their treatment course. I specialize in head and neck cancer, pancreatic cancer, and brain cancers with special emphasis on immunotherapy. I run clinical trials aimed at combining Radiation with immunotherapy to improve outcomes and reduce the side effects.

Care Philosophy
I strive to provide the best care for my patients. I believe in treating the person as a whole, taking every aspect of a patient’s body and health into consideration during diagnosis and treatment.
