Patient Care Philosophy

I believe in doing all I can for my patients and strive to improve their overall outlook on life. In undergraduate college, I majored in physics and also fulfilled the pre-medical requirements. My fondness of people, as well as science, ultimately led me to pursue a career in medicine, and I feel my background in physics is well-suited to the field of radiation oncology.

I believe in using evidence-based medicine and radiation oncology as well as common sense to help patients understand their treatment options and individualized recommendations, rather than making “knee jerk” treatment decisions. We also participate in several clinical trials available at our facility in Boulder.
