Philosophy of Care

I treat patients and families as I would want to be treated and believe in access to healthcare for all. I stand by the value of an unhurried discussion before surgery to explain what to expect, thereby gaining the trust of families. I cannot make the stress go away, but I can provide information and understanding. I hope my background and ability to speak Spanish helps patients feel more at ease.


Dr. Quinonez received his medical and surgical education in Canada. He graduated from medical school in 1993. He trained in general surgery, general thoracic surgery, and cardiac surgery and is a Fellow of the Royal College of Surgeons of Canada. He completed advanced training at the Mayo Clinic and Cleveland Clinic. After returning to Canada, he undertook congenital cardiac surgical training and joined the attending staff at Stollery Children’s Hospital in Edmonton in 2008. He and his wife came to Boston Children’s Hospital in 2012 for one year of additional experience and have been here since that time.
