About Me


I am a pediatric neurologist and epilepsy specialist who treats children and adolescents with epilepsy, drug-resistant epilepsy and focal cortical dysplasia.

I've always been interested in the brain, and I completed an adult neurology residency before "seeing the light" and switching to children. Then, I did additional training at Cincinnati Children’s, so I would be confident practicing in a pediatric hospital.

In our epilepsy surgery group, we are continually adding new ideas and technology to help kids with drug-resistant epilepsy. The program is truly cutting-edge. I believe that every patient presents as a puzzle, and I work with a fabulous team — which includes the patient and family — to solve that puzzle.

Through my research, I want to find a better way to identify areas of cortical dysplasia that causes seizures. I also want to find a better way to identify important language areas in children who need surgery.

When I’m not working, I enjoy spending time with my wonderful wife, our four great kids and our ever-changing assortment of animals. We are an active family — with sports, cycling and tree-house building being some of our favorite activities.
