Meet Our Team

Bariatric surgery can be life changing but is just a tool that requires commitment to ongoing lifestyle changes. By understanding what to expect after surgery, you can better prepare for the lifestyle, health, and emotional changes that come with it. It is important that you stay connected with your healthcare team, follow their recommendations, and enjoy the journey.

Improving your nutrition and incorporating regular physical activity into your lifestyle are equally important to achieving long-term success. The St. Mary's Health Care System Bariatric Surgery team, led by Bariatric Surgeon Aaron Carr, MD, is here to help and promises to be with you every step of your journey—before, during and after surgery. Our goal is to get you back to doing the things you love so you can live and enjoy life to its fullest!

Dr. Carr specializes in general, foregut (anti-reflux), and bariatric surgery. He began his surgical career at the University of California, Davis in 2012 with an emphasis in minimally invasive general and bariatric surgery. In addition, he also performs robotic surgery for many conditions including hernia repairs and colectomies.
