I grew up in upstate New York. From college at Yale through medical school at Harvard and training in pediatrics and pediatric cardiology at Boston Children’s, my passion has been to bring advances in science to bear on the problems faced by patients.
Approach to Care
I am committed to providing the highest quality care for pediatric patients with heart disease, and to advance their diagnosis and treatment through research and innovation.
