Adult Autism Evaluations in Seattle — Finally Get the Answers You’ve Been Looking For

Many adults spend decades wondering why the world feels harder to navigate than it seems to for everyone else. Why social situations leave them exhausted. Why they have always felt fundamentally different — even in rooms full of people who care about them. If this sounds familiar, you are not alone. And an autism evaluation may be the most clarifying thing you will ever do for yourself. I offer comprehensive autism evaluations for adults in Seattle and across Washington State via telehealth. My evaluations are thorough, individualized, and designed to give you real answers — not a rushed checklist.

​​Who Is a Good Candidate for Adult Autism Testing in Seattle?

You may be a good candidate for an adult autism evaluation if you:

• Have always felt like you were watching others from the outside

• Find social interactions exhausting even when you enjoy them

• Have been diagnosed with anxiety, depression, or ADHD but feel like something else is going on

• Rely heavily on routines and feel destabilized when plans change

• Have intense, focused interests that others find unusual

• Struggle with unwritten social rules that everyone else seems to understand intuitively

• Have sensory sensitivities — to sound, light, touch, or texture

• Were told as a child that you were “too sensitive,” “too intense,” or “too much”

• Are a woman who has spent years masking or performing a version of yourself

Autism Masking, Late Diagnosis & ADHD — Why Adults Are Often Missed

Autism looks different in adults than it does in children — and it looks different in women than it does in men. Many adults, particularly women, were never identified because they learned to camouflage their autistic traits early in life. A missed diagnosis in childhood does not mean autism isn’t there.

What Does Adult Autism Testing in Seattle Involve?

My adult autism evaluations are comprehensive, individualized, and typically completed within 4 to 6 weeks of your first appointment.

​

Step 1 — Free 15-minute consultation

We start with a brief phone call to discuss your concerns, answer your questions, and determine whether an evaluation is the right fit for you. There is no obligation and no pressure.

​​

Step 2 — Intake interview

A thorough interview covering your developmental history, current challenges, relationships, work or school experiences, and what has brought you to seek an evaluation at this point in your life.

​​

Step 3 — Testing sessions and collateral interview

One to two appointments using standardized assessment tools validated for adult autism evaluation — including structured clinical interviews and validated self-report measures designed specifically for autism diagnosis in adults. These are not pass/fail tests — they are structured ways of understanding how you think, communicate, and experience the world.

​​

Step 4 — Scoring, interpretation, and report writing

I spend significant time analyzing the results before we meet again. Your report is detailed, clinically sound, and written to be genuinely useful — not just a summary of test scores.

​​

Step 5 — Feedback session

We meet to walk through the findings together. If an autism diagnosis is supported by the evaluation, I will explain what that means for you specifically — and provide clear, practical recommendations for therapy, workplace accommodations, or next steps.

​​

Why an Autism Diagnosis Matters — Even as an Adult

A diagnosis does not change who you are. But it can change everything about how you understand yourself.

​​

Adults who receive a late autism diagnosis often describe the same experience: relief. Suddenly the exhaustion makes sense. The social difficulties make sense. The years of feeling like you were failing at something that came naturally to everyone else make sense.

​​

Beyond self-understanding, a diagnosis can open doors to:

​

• Workplace accommodations under the ADA

• A clearer framework for therapy

• Access to autism-specific support communities

• Better understanding from family members and partners

• The ability to stop masking and start building a life that works for your actual neurology

Autism Masking, Late Diagnosis & ADHD

Many adults — particularly women — were never identified as autistic in childhood because they learned to mask their autistic traits early in life. Autism masking means adapting your behavior to appear neurotypical, often at great personal cost. Decades of masking can lead to exhaustion, anxiety, and a persistent sense that something is fundamentally wrong — even when nothing is visibly "off."

​

A missed autism diagnosis in childhood does not mean autism isn't there. Many adults receive a late autism diagnosis in their 30s, 40s, and beyond — and describe it as life-changing. If you have also been told you have ADHD and wonder whether autism is part of the picture, you may be experiencing ADHD — a co-occurring presentation of autism and ADHD that is far more common than previously understood. My evaluations are designed to assess for all of this.
