Why I Treat Children

I treat children not as little adults but as unique human beings. And I look at each one’s medical condition as a unique challenge. When I can help make a positive difference in a child’s life, it’s especially rewarding.

What I'm Passionate About

I’m passionate about practicing medicine that can help make a positive change in pediatric medicine, and also in the community and society as a whole. Treating HIV and advocacy has been a great way for me to do this.
