get to know me

I chose my specialty because...

I chose pediatric hematology and oncology because cancer and blood diseases are the number one cause of non-accidental death in children in the United States. My focus is ensuring children with these diseases get the best treatment possible. I am also dedicated to finding new and better treatments and cures for childhood brain cancer.

I like working with kids because...

they are full of wonder, they are resilient and they are inspiring.

I chose to work at Dayton Children's because...

the hospital is going through exciting changes and growth that will make this an even better place for children to receive their care.

Dayton Children's is special because...

it is a hospital that has the expertise and facilities of a large pediatric center while maintaining the familiarity and personal attention of smaller hospitals.
