Overview
Open since 2002 in the Dallas–Fort Worth area, this multidisciplinary clinic specializes in neurodiversity across the full lifespan — from 20-month-olds through seniors. Psychological and autism evaluations run through its co-located Illumination Testing Center, while the main practice handles individual therapy, structured social skills groups, parent training, and school advocacy. Clinicians trained at institutions including UT Southwestern Medical Center and Children's Medical Center bring research depth to everyday clinical work.
Families who want autism diagnosis and ongoing support under one roof, especially those with toddlers or school-age children who need thorough testing followed by group therapy or transition planning.
Rather than a single-service model, the team pairs comprehensive psychological assessment with long-term therapeutic support — matching each client by age, support level, and goals. The practice also trains the next generation of clinicians, serving as an active practicum and post-doctoral site.
Getting started means filling out a brief online contact form; staff call back within two business days to map out next steps. All clinicians are out-of-network with insurers — fees are collected at the time of service, and a monthly superbill is issued so families can seek reimbursement on their own. Evaluation deposits are $300, with total fees ranging from $1,750 for toddlers to $3,500 for adults.
