Bio

A surgeon at the Khalili Center for Bariatric Care, Dr. Gregg Kai Nishi has been integrally involved in developing the Center with his colleagues, Dr. Theodore M. Khalili and Dr. Eraj Basseri, whom he worked with at Cedars-Sinai Medical Center. Dr. Nishi brings a wealth of expertise and experience to the Khalili Center. He’s an expert on innovative, minimally invasive surgical techniques and has spoken extensively on the subject, having appeared in a variety of news media, including Good Morning America and the Los Angeles Times. He has trained a number of other bariatric surgeons who have gone on to head up bariatric programs all over the country in their own right. Formerly the Co-Director of the Cedars-Sinai Center for Minimally Invasive and Weight Loss Surgery Fellowship, Dr. Nishi was also an attending surgeon in Trauma Services and Surgical Intensive Care at Cedars-Sinai. He is one of the principal investigators of the FDA trials on a new procedure called TOGA (incision-less weight loss surgery), and is one of only a handful of surgeons in the U.S. who have performed this procedure. Currently Assistant Clinical Professor of Surgery at the David Geffen School of Medicine, UCLA, Dr. Nishi has published widely in such journals as American Surgeon and Bariatric Times, and lectures on weight loss surgery at national and international bariatric surgery conferences. He is the recipient of numerous awards, including the Paul Rubenstein, MD Prize for Excellence in Resident Research Abstract and Awards Presentation; the Society of Laproendoscopic Surgeons Resident Achievement Award; and the Leo G. Rigler, MD Award for Academic Achievement from Cedars-Sinai. An Associate Fellow of the American College of Surgeons, Dr. Nishi is also a member of SAGES, the Society of American Gastrointestinal Endoscopic Surgeons; American Medical Association; and Society of Laparoendoscopic Surgeons.
