Adult ADHD and Autism Diagnostic Assessments

Be assessed by professionals who share in the neurodivergent experience and truly understand

Discover Your True Identity with Affirming ADHD/Autism Assessments

Are you feeling overwhelmed by self-doubt and imposter syndrome, despite extensive research into your neurodivergent identity?

Have you been told you "don't seem autistic" or that you "just need to concentrate more"?

Your path to self-discovery and validation doesn't have to be fraught with uncertainty and skepticism.

Accurate Diagnosis for People who Mask.

We offer quick turnaround on ADHD and autism assessments tailored for individuals who are ready to confirm their neurodivergent identity. Our services are designed for those who want an evaluation without months of waiting.

We are committed to a neurodiversity-affirming process that respects and validates unique neurological differences rather than viewing the differences solely through a deficit-based lens.

What Sets Us Apart: Your Choices, Your Control

When you choose to work with us, you have unparalleled flexibility and control over your assessment process. Here’s how we make it all about you:

  • Meeting Options: Choose between online or in-person meetings to suit your comfort and convenience.

  • No phone calls necessary: Our entire process can be started and your appointments can be scheduled without having to talk to anyone. (but we are here to help if you want to talk first!)

  • Custom Packages: Select the package that fits your needs and budget, with varying levels of report detail and pricing

Not looking for a formal assessment or diagnosis?

Formal assessment is expensive and is not an option for many people. If you would like to have a professional look over your self-report online test scores, ask some deeper questions and answer your questions, we are happy to meet with you for a one-time session ($200 for 55 minutes) and let you know if we think your scores and profile are consistent with autism.

For many people this is all they need.

For official diagnosis options, please see the package options below:

Package Options:

Essential Evaluation

$600

Perfect for those who need a straightforward confirmation, our Essential Evaluation includes comprehensive ADHD/Autism testing, “official diagnosis” and a two-page report. This abbreviated report provides a clear diagnosis and recommendations to help you move forward.

This package is best for those who just want to know.

Comprehensive Evaluation

$900

For those wanting full reports and a deeper understanding of each of the assessment tests, our Comprehensive Evaluation includes the same thorough testing as the Essential Evaluation but with a detailed, multi-page report. This in-depth document extensively covers the scores of each of the assessments, your diagnosis and symptoms.

This package is a good option for those who want to present the report to other medical professionals who might need the results of the specific testing tools.

Advanced Evaluation

$1900

Our Advanced Evaluation is ideal for those who want the most extensive assessment that includes the ADOS-2 evaluation, a gold-standard tool widely recognized by medical professionals. This package is best for those who want to present the report to other medical professionals. However, we prefer using the MIGDAS-2 instrument for its sensitivity to neurodivergent and twice-exceptional experiences as well as inclusivity across all genders, races, and ethnicities. (see more about this on our FAQ page).


This package is best for those who who want to present the report to other medical professionals outside of the neurodivergent-affirming network.

Note: Premera, Kaiser and Regence can be billed for a small portion of the fee. This will reduce the cost by around $100-120. Please contact us for more information.
