Philosophy of Care

I treat patients and families as I would want to be treated. I believe in the value of an unhurried discussion before surgery to gain mutual trust. I know I can’t take the stress away, but I can provide information and understanding. I hope my background and ability to speak Spanish will help some patients feel more at ease. Finally, I believe everyone should have access to healthcare.


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 and have been here ever since.
