“My goal is to provide excellent, personalized, safe care for patients requesting weight-loss surgery,” Dr. Cahill said. “The benefits of surgery include sustained weight loss and improvements in co-morbid conditions, daily living activities, sense of self and attitude about their lives and healthy lifestyles.”

Dr. Cahill has dedicated his practice to weight loss surgery and specializes in minimally invasive surgical (laparoscopic) techniques using the da Vinci Xi robotic surgical system for the treatment of obesity. He performs Roux-en-Y gastric bypass, gastric sleeve and biliopancreatic diversion with duodenal switch procedures.


“I strive to assist patients on achieving a realistic goal weight, a resolution of medical problems, a positive attitude about their health and an overall improved lifestyle,” Dr. Cahill said.


His team of professionals, which includes a medical weight loss physician, a clinical psychologist, registered nurses, registered dietitians and insurance specialists, carefully prepares their patients in the weeks and months before surgery to ensure physical, emotional and psychological readiness to maintain a lifetime of good health. Because attitude plays a vital role in successful outcomes, ongoing support is available to patients at no additional cost.


If you would like to lose significant weight with bariatric surgery assistance, Dr. Cahill

can help you sharpen the tools you need to take control.
