About Grand Health Partners

At Grand Health Partners, we believe that people who succeed in making their lives healthier are happier. Our mission is to help people improve their health through a well-rounded approach to weight loss. To better fit your lifestyle and your needs, we provide both surgical and non-surgical weight loss programs. Our programs are led by a group of independent bariatric surgeons who have a passion for providing excellent patient care. Weight loss is our specialty. We will provide coaching for dietary, behavioral, and exercise habits while you are monitored by licensed bariatric physicians. Because we understand that genetic, social, cultural, and emotional factors lead to obesity, our patients are properly supported and equipped throughout their weight loss journey.
