Comprehensive diagnostic psychiatric evaluation with a focus on children and adolescents. My background in pediatrics and developmental disabilities is helpful is disentangling developmental concerns from more acute psychiatric disturbance. Within the spectrum of mental health issues, I have special expertise in assessment and management of anxiety disorders, obsessive compulsive disorder, tic and Tourette disorder, mood disorders and ADHD. Treatment skills include up to date psychopharmacology and cognitive behavioral therapy.

What do clients have to say about you?

1. Dr. Gellar is one of the top OCD doctors in the country. My child had suffered tremendously from OCD, anxiety and depression. We took him to numerous doctors. Nobody had an answer or a treatment plan, and worse, didn't really seem to care. Dr. Gellar is a God send. Having him on our side is something that is hard for me to express in writing. He saved our son and also us, as parents. He is a brilliant doctor and a kind man. He is easy to reach and has even returned calls on weekends.

2. We have been working with Dr. Geller for many years and he has been an outstanding support. I highly recommend him.

3. Dr. Geller is an exceptional psychiatrist. He is very accessible at his private practice.
