Get to Know Me

I am a general pediatric cardiologist at Nemours Children's Health with clinical interests in acute care, general, and preventive cardiology. I am the medical director for the Nemours Project ADAM affiliate, which works to implement cardiac emergency response plans in schools and youth sports leagues. I volunteer with the American Heart Association (AHA) to advocate for access to and funding for AEDs and CPR training for youth, and am involved in research related to disparities in sudden cardiac arrest preparedness. I also have a passion for medical student, resident, and fellow education and devote considerable time to these endeavors.

I live in the Philadelphia suburbs with my wife and two daughters. I love jazz music and collecting vinyl records as well as playing basketball and squash.

Why I Treat Children

I chose a career in pediatrics because I love interacting with kids and teenagers. There is no better way to spend a day at work. It is also incredibly rewarding and meaningful to teach and support and reassure parents. As a pediatric cardiologist, I take seriously the responsibility that I have to the child and their parents and get incredible joy out of helping a family through whatever brought them to my clinic or hospital.

What I'm Passionate About

I am a huge believer in prevention and preparedness with respect to cardiac disease (particularly in youth). Childhood is the ideal time to consider the factors that set the foundation for lifelong health: healthy diet, exercise, sleep, blood pressure, cholesterol, diabetes, smoking, and healthy weight. There are seemingly endless forces in our society that make maintaining this solid foundation difficult. It is our job as pediatricians to help combat these forces and set kids up for success.

How I Try to Make A Difference

Each encounter with a patient and family is an opportunity to make a life better — whether we move closer to repairing a heart condition that the child was born with or engage in an honest conversation about the foundations of a healthy lifestyle. My responsibility is to create a welcoming space to share the information and gather the data needed to help my patients and their families. Going to the pediatric cardiologist, or being admitted to the hospital, is scary. I try to be a supportive and reassuring presence for patients and families during this challenging time.
