Meet Our Heart Team

University Children’s Health Heart Center offers your child best-practice congenital cardiac care with an empathy and kindness that families want and our patients deserve. Our Heart Center offers some of the best outcomes in the nation, and we believe that’s due to the exceptional skill level of our multidisciplinary pediatric cardiac specialists, as well as our dedication to treating each patient as family. Our team of cardiothoracic surgeons, pediatric intensivists, pediatric cardiologists, cardiac nurses and heart health professionals, provide the highest quality of care for this special group of patients.
