Patrick Chiasson, MD, MA, FRCS, FACS 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.  Dr. Chiasson was initially recruited to the University of Arizona in Tucson, AZ and then moved his practice to Northwest Medical Center where he established the Southern Arizona Center for Minimally Invasive Surgery and developed the hospital’s Surgical Weight Loss Program.  He is the past President of the Arizona Chapter of the American Society for Metabolic & Bariatric Surgery.  Dr. Chiasson has numerous publications to his credit that address such issues as Minimally Invasive Surgery techniques and outcomes, Health Policy, Medical Ethics, and Health Law. He is also an educational consultant for Ethicon Endo-Surgery.


“(Dr. Chiasson’s) bedside manner is impeccable and he has an uncanny way of making you feel like you’re the MOST IMPORTANT person in the world to him; that he would do anything for you he possibly could…Dr. Chiasson is the BEST doctor I’ve ever had the privilege of knowing.  He removed my gall bladder a year after my weight loss surgery and I entrusted him with my life twice…I am at goal now…He literally gave me back my life!  Both his surgical competence and bedside manner are SUPER.”  Maggie F.
