Why I Treat Children

I have always liked children. I decided to become a doctor to help them as best as I could. And, when I was a medical student, I became intrigued with the lungs and breathing. The young pulmonary patients I encountered — and the physicians taking care of them — drew my interest to specializing in children's lung diseases.

What I'm Passionate About

I am passionate about the patients and families that I see. They have taught me strength and persistence, because I see those with chronic diseases who are so strong and persist and manage their disease and find ways to live with it. I think they bring us their friendliness and their happiness, and their happiness helps us all be happy in the care that we try to provide them.

How I Try to Make A Difference

We have a great team of physicians, nurses and staff, and it is exciting to be able to provide such great care for kids. We all strive hard to talk with children on their level and to explain things to them, and to work in a kid-friendly manner.
