Overview
A solo practice in Cypress, TX, Nash Psychological Services is run by Dr. David L. Nash, a licensed clinical psychologist with three decades of clinical experience — more than nine of those years focused on autism and ADHD diagnosis across the lifespan. The practice specializes in diagnostic evaluations for ASD and ADHD, serving both children and adults. PSYPACT APIT membership lets Dr. Nash extend virtual assessments to families in most states beyond Texas.
Families in the Cypress/Houston area, or anywhere in PSYPACT-eligible states, who need a thorough ASD or ADHD diagnostic evaluation from a seasoned PhD psychologist rather than a large clinic setting.
Each evaluation is individualized, with documentation and client communication routed through a HIPAA-compliant secure portal. Appointments can be completed in person at the Cypress office or fully via telehealth for out-of-state clients.
Evaluations are self-pay at $910; BCBS and Cigna are accepted in-network, and Dr. Nash provides superbills for families seeking out-of-network reimbursement. Scheduling is available by call or text.
