Philosophy of Care

In serving my patients, I employ evidence-based radiation therapy that is tailored and individualized for each unique patient. I strive to minimize side-effects from treatment, all with a goal of improving my patients’ quality of life. I feel it is an absolute privilege to care for patients with cancer and their families, and I am constantly in awe of my patients’ strength and insight.
