Get to Know Me
I grew up in the New York City area. As a child, I was something of a science geek. I enjoyed applying what I learned to real life situations. As a pediatric cancer specialist, I always focus on helping kids with cancer and brain tumors enjoy the best possible quality of life.Why I Treat Children
I have tremendous respect for the children in my care. Although most are very sick, they handle adversity amazingly well. They don’t complain and just want to be done with treatment so they can go on with their lives.How I Try to Make A Difference
I try to make a difference through hope and healing. The fact that Nemours is so active in cancer research means we have access to experimental treatment options that offer real hope for a cure. Just as important, we do everything we can to make a terrible process less terrible by alleviating any suffering.Education & Training
