Gerald A. Cahill, MD

"My goal is to provide excellent, personalized, safe care for patients desiring weight-loss surgery. I strive to assist patients in achieving a realistic goal weight, thus achieving a positive attitude about their health and an overall improved lifestyle." The benefits of bariatric surgery include sustained weight loss and improvements in co-morbid conditions. This will improve daily living activities and a sense of self and attitude about their lives and healthy lifestyles."
