About psychologists

Psychologists hold a doctorate (PhD, PsyD or EdD) and a state license. They provide therapy and are the only clinicians on this list trained to run formal psychological and diagnostic testing. Most cannot prescribe.

Before you call

Ask whether they're taking new patients, which insurance plans they're in, what a session costs without insurance, and whether they see people by video. You can check any clinician's license with your state licensing board, and their NPI record at the CMS NPI Registry.
