Get to Know Me

I’m a primary care pediatrician at Nemours Pediatrics in Seaford, Delaware and I love what I do. I enjoy helping people feel better, and watching my patients grow up healthy and happy. You could say it runs in the family, because I’m married to a family practitioner, and we have three wonderful children of our own.

Why I Treat Children

I love treating kids! I am continuously amazed by their resiliency. Even in my medical training, I always felt connected to the children I cared for – and their parents – so I chose pediatrics as my medical career.

What I'm Passionate About

I get tremendous personal satisfaction from helping ill children get better. One of my proudest moments was when a newborn I had resuscitated came in to the office for the first time for a routine wellness checkup. Every time I see my patients persevere in school or participate in an extra-curricular activity, I know I’m making a difference.
