Kurt Roberts, MD, FACS, is a Board Certified General Surgeon who is fellowship-trained in minimally invasive surgery. With extensive experience in laparoscopic bariatric surgery and gastric banding, he is dedicated to helping individuals with morbid obesity reach healthier weights.

He is also dedicated to improving the lives of individuals suffering from acute and chronic gastrointestinal conditions, such as hernias, gall stones, achalasia and pancreatitis.

Dr. Roberts is committed to advancing minimally invasive surgical techniques so that patients have only one or even no external incisions, allowing them to have better aesthetic outcomes with little or no scarring, shorter recovery times, and less post-operative pain than even traditional minimally invasive surgeries. Advanced minimally invasive surgery pioneered by Dr. Roberts includes Single Port Surgery or Single Incision Laparoscopic Surgery (SILS) - the removal of the appendix or gallbladder through only one small incision hidden in the umbilicus (belly button). He also performs scarless surgery (Natural Orifice Transluminal Surgery - NOTES) through natural orifices such as the stomach or vagina for patients with appendicitis or symptomatic gallbladder disease.

He specializes in laparoscopic gastrointestinal surgery; laparoscopic bariatric surgery; laparoscopic gastric bypass surgery and especially laparoscopic gastric banding; laparoscopic repair of inguinal hernias and abdominal wall hernias such as incisional hernias or ventral hernias; laparoscopic gallbladder surgery; cholecystectomy; laparoscopic surgery for reflux and achalasia (esophagus); laparoscopic colon surgery; laparoscopic emergency general surgery; endoluminal therapy (a revolutionary approach to Gastroesophageal Reflux Disease - GERD); laparoscopic surgery for pancreatitis.
