Overview
Autism Diagnosis & Assessment in Austin
South Austin families looking for a full psychological workup have a small practice off Brodie Lane to turn to, one built by a psychologist who spent years testing for a group before opening on her own in 2023. The team today includes a licensed psychologist, a second doctoral-level psychologist, and a licensed psychological associate, together covering autism, ADHD, learning concerns, and broader emotional or behavioral questions for kids through adults. Every visit follows the same structure: an interview with the client and caregivers, formal testing, then a sit-down feedback session that walks through a written report.
Best for
This practice suits families who need a formal, report-backed diagnosis for autism, ADHD, or a learning difference before moving into services or school accommodations.
Their approach
Testing here follows a consistent rhythm: caregiver and client interviews first, then standardized measures, then a feedback meeting where the psychologist walks the family through the full written findings.
What to expect
Scheduling happens by phone or email, and the process wraps up with an in-person session covering the written report; the website doesn't list specific fees or insurance panels, so it's worth asking directly.
