After finishing training, Dr. Harris joined Radiation Oncology Associates in 2010.

“I chose to pursue a career in radiation oncology because it allows me an opportunity to apply my technical abilities and interests to the care of patients. I am deeply fascinated and, at the same time, humbled by the field of oncology. I consider it a great honor to take part in the lives of cancer patients and enjoy working with teams of talented and caring practitioners to better serve my patients.”
