Introducing Our New Bariatrician, Nina Gray MD


Nina Gray MD

Dr. Nina Gray is a bariatrician specializing in nonsurgical weight management care. Her passion for preventative medicine fuels her to treat obesity as a chronic condition – no different from diabetes or hypertension.

Dr. Gray is excited to expand her practice as part of the TriHealth Weight Management team. With a priority on physical and emotional wellness, she values the importance of personalized care for each patient. Dr. Gray reminds patients that weight loss treatment 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.

Call 513 862 4957 to schedule an appointment with Dr. Gray.
