Clinical Interests
I enjoy treating all forms of cancer and benign conditions for which we use radiation. My particular interests are brain, spine, head and neck, skin, breast, prostate, and thoracic tumors.

Care Philosophy
I strive to offer each of my patients and their families the best possible care. I think this starts with listening and prioritizing their values. Our team then works towards a treatment plan that meets these values while employing current evidenced based practices. I aim to remain available and support my patients and families throughout their treatments and follow-up. My primary practice is located at Cherry Creek Medical Center, and I also spend time at our Anschutz Medical Campus location.
