I am a cancer surgeon with a clinical and research focus in melanoma and other advanced skin cancers as well as sarcomas of the skin and abdomen. I completed my Surgical Oncology training at MD Anderson Cancer Center in Houston, Texas. I have extensively researched melanoma prevention, early diagnosis, and treatment. I am actively involved in local, regional, and national groups that focus on improving the treatment for melanoma patients. I am an investigator for several local melanoma studies that provide options in treatment for more advanced melanoma. My passion is patient-centered care and I work to understand the specific needs and wants of each patient. I teach medical students and surgery residents and I enjoy educating my patients about their illness. I am actively involved with a melanoma survivor group which includes planning of our yearly melanoma walk to support melanoma patients and research. Outside of the hospital I enjoy the nature beauty of Utah and spending time with family.
