### What is a psychologist?

Our psychologists are independently licensed providers who have completed their doctoral degree (which means they are a doctor of philosophy or psychology), including a pre-doctoral internship and postdoctoral fellowship. They are qualified to do diagnostic evaluations, therapy, and psychological testing. Psychologists do not prescribe medication, but they are able to directly refer families who need that service to a Brightline psychiatrist or psychiatric nurse practitioner.
