Obtaining a diagnosis is difficult for adults. Often, diagnosticians only work with children, or they have a dated and incomplete notion of how autism looks in adults– a fact that is especially true for women and non-binary autistics.

This list has been compiled from a variety of sources and has only been partially vetted. Many of the names on this list were submitted by adults from various social media and information has been added on good faith.

If you have been diagnosed and do not see your provider on this list, we would appreciate if you would share that information so that others in your area can find quality practitioners. Please leave a comment or email david.gray-hammond@neuroclastic.com with the diagnostician’s name, location, and any contact information you have.

If you’ve had a positive or negative interaction with any of the providers on this list, please let us know at the email address above so we can note that information on the list.
Names in red bold print have been verified by NeuroClastic as reliable.
