About Atlanta Bariatrics

If you are overweight and have tried everything imaginable to lose weight through conventional means such as dieting, exercise, behavior therapy, and/or drugs, but have been unsuccessful in your attempts, then weight loss surgery may be right for you. Atlanta Bariatrics specializes in weight loss surgery for morbidly obese patients.

Atlanta Bariatrics at Johns Creek Surgery, PC has served the Atlanta community for over 15 years offering the most comprehensive treatment for patients suffering from obesity. Representing the best in their fields, Atlanta Bariatrics’s surgeons, Dr. Christopher J. Hart and Dr. William H. Johnson, bring special expertise to their patients to treat obesity by modification of the gastrointestinal tract to reduce nutrient intake and/or absorption.
