Grey Matter Psychological Assessment is different.
At Grey Matter Psychological Assessment, we know that you want to understand your symptoms and finally live up to your potential. In order to live that life, you need clarity on whether you have ADHD, autism, or some other learning difference and what you can do to manage it. The problem is: not all psychological testing is created equally. You might find yourself waiting months for your results or getting bland and unhelpful feedback. This leaves you feeling confused and frustrated about your next steps. You should be able to understand your neurological and psychological processes.
You might get mixed up in the differences between anxiety, depression, ADHD, ADD, and trauma symptoms. It makes school, work and relationships feel out of control. Our collective of psychologists provides approachable, thoughtful, and thorough psychological testing.
What is holding you back?
Testing is too expensive.
We provide the most cost-effective testing in Los Angeles. You deserve to have access to testing without the overwhelming burden of cost. For any of our services, we offer superbills, which can be turned into your PPO insurance for reimbursement, and payment plans.
I’m too complicated.
If you’ve felt that no one has been able to help you, this assessment will finally answer those nagging questions about your psychological functioning. If it doesn’t, we’ll continue to search for answers with additional tests and assessments.
I need answers immediately.
Testing and assessment do take a little bit of time and scheduling, and you can expect your results and/or feedback session about one month after testing. Need the results faster? Just let us know during your consultation call how to best accommodate you.
Testing takes too long.
Testing can be scheduled to adjust to your specific needs. It is possible to break up the testing sessions, get your feedback more quickly than normal, or arrange for other accommodations. Schedule a consultation to troubleshoot concerns.

Your pain is real. If you’re tired of uncertainty and want a clear, data-informed understanding of what’s happening, we’re here to help.
