Clinical Interests
I am a Colorado native who loves caring for the people of my home state and region. Clinically, I have a special interest in advanced thyroid cancers, salivary gland cancers, and rare cancers of the head and neck, though I enjoy caring for head and neck squamous cancers, as well. I also have a passion for medical education and am the Program Director for the University’s Hematology/Oncology Fellowship.

Personal Interests
I am an avid Denver sports fan and enjoy music, travel, and spending time with my family outside of work.
