An area of interest for me is sports medicine as I can use my experience in professional baseball to better care for our patients. As a Physician Assistant I work directly with Dr. Peatman to assist him with his clinic and surgical practice.

Specifically I assist with total joint replacement, shoulder, hip and knee arthroscopy and sports medicine surgeries.

In clinic my work entails taking medical histories , diagnosing patients, performing pre operative and post operative exams, administering injections, ordering and interpreting imaging studies and ordering medications.

When I'm not seeing patients I hiking, camping, traveling, reading and spending time with my family.
