"What I enjoy most about Orthopedics is it allows me to utilize my training and experience to help our patients to resume more active and healthy lifestyles."

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 like hiking, camping, traveling, reading and spending time with my family.
