We care for children with autism, ADHD, genetic disorders, and other challenges to mental, social, emotional, and academic development.


Autism Spectrum Disorder can take many different forms along a spectrum from mild to severe. In general, autism affects communication, social skills, and the ability to self-regulate.

Dr. Gary Feldman has specialized in diagnosing and designing tailor-made support plans for children with autism for over 15 years. If you are concerned about your child's developmental progress, or would like to get them evaluated for autism, click below.


Attention-Deficit/Hyperactivity Disorder ​is one of the most common neurodevelopment disorders affecting children, and may be associated with difficulty paying attention, poor impulse control, and high levels of activity. Because there is no distinctive test to diagnose ADHD, experienced physicians look at a variety of factors that usually require a consultation and thorough history. After diagnosis, interventions can go a long way to help children thrive at school and in the home.


There are a number of different neurological and genetic factors that can affect learning and academic success. In addition to challenges with processing, these factors can affect organization, time management, abstract reasoning, memory, and attention. We do consultations for evaluation of a variety of learning disabilities.


We evaluate and coordinate care for:

  • Cerebral palsy

  • Genetic disorders

  • Developmental delay

  • Intellectual disability

  • Other challenges to mental, social, emotional, or academic development

Dr. Gary Feldman has extensive experience developing care plans for a wide variety of behavioral and developmental conditions in children. To learn more about how we can help, click below:

"Dr. Gary Feldman is the most incredible doctor I have ever met. Not only does he always make time to help my 7 year old son but he is so sympathetic to our situation, so kind and knowledgeable. I live kind of far from him but it is always worth the drive to go and see him and I never leave disappointed. He is so amazing with my son and never rushes any time we get with him, he answers all of our questions with a lot of thought and is extremely informative.


He never criticizes and always supports and gives advice, provides many resources and is always there to support in any way he can. He always listens to our concerns and takes his time helping us in the best way he can. He is patient, professional and purely amazing with my son. My son loves him too!! He always makes us feel comfortable and goes out of his way to help us in the office or by phone and is seriously the BEST!! I am so thankful that he is helping my son because he is seriously special and amazing at what he does. Anyone would be lucky to have him helping them!!"
