Dr. Nina Gray is a bariatrician specializing in nonsurgical weight management care. Her passion for preventive medicine fuels her to treat obesity as a chronic condition—no different from diabetes or hypertension. While serving as chief resident of her family medicine residency, Dr. Gray developed a template for primary care physicians to use to address weight issues with patients. This template has since been adopted throughout the TriHealth system.
Now backed by a multidisciplinary team of physicians, nurses and dietitians, she customizes treatment plans to fit each individual's needs. Dr. Gray reminds patients that this is a life change, not a diet, and is motivated by seeing small incremental changes in patients that will help achieve and maintain lifelong success.
