Overview
Autism Diagnosis & Assessment in Lewisville
Opened in 2009 in Lewisville, TX, this independent neuropsychology practice has built a team of lifespan, pediatric, and adult neuropsychologists backed by multiple credentialed psychometrists. Evaluations cover autism spectrum disorder, ADHD, developmental delays, dyslexia, learning disabilities, traumatic brain injury, and neurodegenerative conditions for ages 2 through senior adult. Every assessment is built around the individual's specific presentation — no standardized template applied across the board.
Best for
Children and adolescents whose families want a rigorous, individually tailored neuropsychological evaluation for autism, ADHD, developmental delays, or learning difficulties — with the depth of a private specialty practice.
Their approach
Standardized assessment tools are selected specifically for each patient to pinpoint cognitive, behavioral, or learning dysfunction, rather than running a fixed battery on everyone. The team pairs neuropsychology expertise with school psychology backgrounds, giving families practical, school-ready recommendations alongside the clinical findings.
