Dr Walter Sartor

Walter Sartor, MD, FACS

Founder of Louisiana Center for Weight Loss Surgery
Dr. Walter Sartor has been providing weight loss surgery to patients since 2003.  In 2007 he saw the need for a comprehensive and local weight loss surgery center.  In partnership with P&S Surgical Hospital and St. Francis Medical Center, he opened the Louisiana Center for Weight Loss Surgery (LCWLS).  He has continued to provide Gastric bypass and now provides Sleeve Gastrectomy and adjustable banding as weight loss surgery options.

In 2010, The Louisiana Center for Weight Loss Surgery and Dr. Walter Sartor were recognized as a Bariatric Surgery Center of Excellence® by the American Society of Metabolic and Bariatric Surgery.  The ASMBS Bariatric Surgery Centers of Excellence® program was created to recognize bariatric surgery centers that perform well and pursue a total commitment to a high level of bariatric care. Clinical evidence shows that the most experienced and best-run bariatric surgery programs have by far the lowest rates of complications.
