I can think of no greater profession than pediatric cardiology.
Dr. Madsen

“I can think of no greater profession than pediatric cardiology. The opportunities for positive and lasting impact are evident everywhere and across the lifespan. It is a privilege to provide the most advanced clinical care for the benefit of newborns with congenital heart disease. It is inspiring to assist patients and families as they navigate the complex journey from child to adult. It is with deep gratitude that I recognize the privilege of being a pediatric cardiologist.”
