Comprehensive Psychological & Developmental Assessments 


Developmental & Educational Psychological Services provides high quality comprehensive assessments to identify psychological and developmental conditions for individuals from early childhood to adulthood.


Autism is neurobiological developmental disability that is present before the age of 3 years. Autism impacts the development of the brain in the areas of social interaction, communication skills, and the individual may have a restricted range of interests or repetitive behaviors.


Attention Deficit Hyperactive Disorder is a neurodevelopmental disorder that affects millions of children worldwide and often continues into adulthood. ADHD is highly treatable and can be accurately identified using objective measures.

Learning Disabilities

A specific learning disability is present when there is a significant discrepancy between an individual’s cognitive development and academic development. Accurate identification of a learning disability is essential to support academic development.

Developmental Delay

A clear understanding of your child’s developmental levels can inform  parenting strategies and determine if intervention is needed.
