About me

Welcome and thank you for visiting my website. I am Brent Jennewine, an orthopedic surgeon based in Casper and Douglas, Wyoming and serving Central and South Central Wyoming as an employee of Memorial Hospital of Converse County. Originally from Ohio, my medical and orthopedic surgery training has taken place at multiple prestigious institutions throughout the United States before establishing a home in Casper, Wyoming with my wife and our two huskies. In my free time, I enjoy fly-fishing, skiing, golfing, and hiking.

While I was completing my general orthopedic surgery training at the esteemed Campbell Clinic in Tennessee, I discovered my passion for shoulder and elbow surgery. I pursued this passion with additional, specialized training through a fellowship in shoulder and elbow surgery at the Fondren Orthopedic Group and Texas Orthopedic Hospital in Houston, Texas. My mission is to provide you the best possible outcome through high-quality, personalized, and patient-centric orthopedic care. Improving your quality of life is always my top priority.
