Dr. Chiasson is a Canadian trained surgeon. He has certification from both the Royal College of Surgeons in Canada and the American Board of Surgery in the United States. He received his medical education at McGill University in Montreal, PQ, a Master’s degree from the Institute for the History of Medicine at the Johns Hopkins University in Baltimore, MD, and his general surgical training at Dalhousie University in Halifax, NS. Finally, he completed his sub-specialty training in advanced laparoscopic surgery at the University of Toronto’s highly regarded Center for Minimally Invasive Surgery.

He is a member of the American Society for Metabolic and Bariatric Surgery, the American Foregut Society, and SAGES. He is the past President of the Arizona Chapter of the American Society for Metabolic & Bariatric Surgery. He serves as a consultant for Ethicon Endosurgery / Torax and is involved in the education of surgeons to perform the LINX procedure. Finally, he has numerous publications to his credit that address such issues as Minimally Invasive Surgery techniques and outcomes, Bariatric Weight Loss Surgery, Health Policy, Medical Ethics, and Health Law.

Dr. Chiasson strongly believes that Minimally Invasive Surgery will continue to evolve with the goal of greatly reducing or eliminating the trauma related to surgery. It is his hope that patients come away from their surgical experience feeling that they have received “cutting edge” surgical care.
