Dr. Jossart’s Philosophy

Dr.Gregg H. Jossart, MD

Director, Minimally Invasive Surgery, CPMC

Dr. Jossart has specialized in endocrine and metabolic diseases since 1993. Because bariatric surgery has been proven to cure obesity-related diabetes, he started performing the laparoscopic Roux en Y Gastric Bypass in 1998, during his fellowship in Laparoscopic Surgery. This early experience exposed him to a range of techniques that ultimately allowed him to perform Duodenal Switch and Sleeve Gastrectomy procedures laparoscopically. He has been performing these procedures since 1998 and on more than 3,000 patients. His interest in curing obesity and diabetes coupled with his expertise in laparoscopy have enabled him to help thousands of men and women to achieve their weight loss goals with the least amount of discomfort. He is one of the few surgeons worldwide who offers the full range of bariatric surgical procedures (Duodenal Switch, Sleeve Gastrectomy, Gastric Bypass, LAP-BAND®, REALIZE® Band, Band to Sleeve, Revisions) and most abdominal procedures laparoscopically.

He has served as the Director of Minimally Invasive Surgery at California Medical Center since 1999. He is a diplomat of the American Board of Surgery and a fellow with the American College of Surgeons. He is a member of the American Society of Metabolic and Bariatric Surgery and the Society of Gastrointestinal and Endoscopic Surgeons.

He is committed to helping the patient to make a fully informed decision and supporting them afterwards, and he expects the patient to follow all of the recommendations he provides. Together, the common goal of attaining the desired weight and alleviating medical problems can be achieved.

Dr. Jossart’s patients appreciate his eagerness to listen to their individual concerns, his ability to provide the kind of guidance that can only come from an exhaustive knowledge of their choices, and his commitment to see them through their post-surgical challenges. Dr. Jossart’s philosophy is one of accountability—for both patient and surgeon.
