Dr. Rives prioritizes minimally invasive and robotic techniques whenever possible to reduce postoperative pain and expedite recovery for his patients.

His work has been recognized nationally, including receiving the Top Video award at the American Society for Metabolic and Bariatric Surgery annual meeting in 2025. When he's not in the hospital, Dr. Rives enjoys spending time with his family, cycling, and hiking.
