Dr McMahon is the most caring and thorough physician you can ask for!! Our son had a previous bad experience and a failed surgery the first time . Dr. McMahon and her team were the only ones who would take on such a challenge. Our experience was overall excellent at Phoenix Children's Hospital with the entire Pectus team. We strongly recommend coming to Dr. McMahon. She went above and beyond in the care of our son. She has instilled such confidence in him after his surgery. It completely changed his life.
