Get to Know Me

Dr. Gregory Witkin is a licensed clinical neuropsychologist and a clinical assistant professor of pediatrics at the Sidney Kimmel Medical College of Thomas Jefferson University. While he sees patients with a wide variety of medical conditions, he has a specialty in working with children with hearing loss.

Why I Treat Children

I originally planned on working with adults, but once I started working with children, I never looked back! I enjoy the energy children bring, and I am always amazed at kids’ insights and resilience.

What I'm Passionate About

It sounds nerdy, but I am passionate about neuropsychology and working with the patients I serve. Further, as a Gallaudet graduate, I am passionate about the Deaf community and advocating for children with hearing loss. I am also passionate about the NY Rangers!

How I Try to Make A Difference

My ultimate goal is to empower families to advocate for their children’s needs. I recognize that parents are the experts on their child’s unique complexities — my role is to help families better understand their child’s strengths, in addition to challenges. Families often have multiple concerns, which affect one another. I provide a comprehensive look at the child, and then provide families with information, recommendations and resources that they can use to help their child achieve to their fullest potential.
