Why Families Choose AutismCOE

Hospital systems and developmental pediatricians in Maryland routinely quote 6–12 month waits for an autism evaluation. Early diagnosis means earlier intervention — and research consistently shows earlier intervention drives better outcomes.

A Belief In Every Child’s Potential

Licensed Psychologist-Led

Every evaluation is conducted and signed by a licensed psychologist with expertise in early childhood development — accepted by insurers, schools, and physicians.

Gold-Standard Tools (ADOS-2)

We use the most respected, research-validated assessment instruments, administered in a gentle, play-based setting your child will actually enjoy.

A Report You Can Use Immediately

Your comprehensive written report supports insurance authorization, IEP and school services, and therapy planning — delivered within 2 weeks of testing.

One Team From Diagnosis to Therapy

If your child qualifies, they can move directly into our ABA, speech, and early intervention programs — no second provider search, no second waitlist.

Is an Evaluation Right for Your Child?

Signs Parents Often Notice First. You know your child better than anyone. If any of these feel familiar, an evaluation can give you clear answers — whatever the outcome.

Limited eye contact, or not responding to their name by 12 months
Repetitive movements such as hand-flapping, rocking, or spinning
Preferring to play alone, or difficulty engaging with other children
Delayed speech, loss of words, or limited gestures like pointing and waving
Strong reactions to sounds, textures, lights, or changes in routine
Intense, narrow interests or lining up toys instead of pretend play

A diagnosis isn’t a label — it’s a roadmap. And if it’s not autism, you’ll know that too.

3 Steps to Clear Answers

Our staff supports you at each step — including all insurance paperwork. 

1

Your Initial Consultation

We sit down with you (in person or by phone) to hear your story, review your child’s developmental history, and verify your insurance benefits. A no-judgment zone where your observations are valued.

2

The Evaluation

Using gold-standard tools like the ADOS-2, our licensed psychologist interacts with your child in a gentle, play-based session — observing communication, social, and behavioral patterns to build an accurate picture.

What Happens After Diagnosis

A Diagnosis Is the Beginning — Not the End

Most families face a second waitlist after diagnosis: finding an ABA provider, verifying insurance again, and waiting months for therapy to begin. At AutismCOE, your evaluation and therapy team are under one roof.

If your child receives an autism diagnosis, we can begin insurance authorization for ABA therapy the same week — center-based or in-home, in Columbia and across Maryland.

Testimonial

Autism Center of Excellence has been a life-changer for our family. Our son was diagnosed with autism at 6 years old and we were overwhelmed and scared. Autism COE helped us understand his needs and strengths and provided him with individualized and evidence-based ABA therapy. He has learned so many skills and gained so much confidence. We can’t thank them enough for their support and guidance.

Parent of K*, 6 years old.
