Atlanta General and Bariatric Surgery Center (AGBSC) – Atlanta’s Premier Weight Loss Surgery Center

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. AGBSC specializes in weight-loss surgery for morbidly obese patients.

AGBSC 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, our surgeons, Dr. Christopher J. Hart and Dr. William H. Johnson, and Dr. Michael Williams bring special expertise to their patients to treat obesity by modification of the gastrointestinal tract to reduce nutrient intake and/or absorption. For individuals who have been unable to achieve significant weight loss through diet modification and exercise programs alone, bariatric surgery may help you attain a more healthy body weight.

A Comprehensive Program

At AGBSC, our program is carefully structured to support you through every step of the weight loss journey and beyond. Our staff of professionals are here for you – from doctor to dietitian. Every member of our team is dedicated to providing the highest quality of surgical weight-loss management in a caring and compassionate setting.

As a result of our extensive bariatric experience, we provide multiple surgical options to our patients, including laparoscopic gastric bypass, laparoscopic sleeve gastrectomy, LAP BAND®, and band plication. You will have the time to explore the options best for you and make a carefully considered, informed decision. We are all committed to helping you achieve success with personal weight loss goals.

However, we believe that bariatric surgery is only one part of a comprehensive plan to help you lose weight and become healthier. That is why our expert, friendly staff offers regular support groups, personal attention from a registered dietician, advice, and availability of exercise classes, informative seminars and more.

The Personal Touch

When you visit our practice, you’ll be surrounded by a patient-centered, compassionate team of bariatric professionals dedicated to helping you fight the war against obesity. Our entire staff is committed to assist you on your weight loss journey.
