Despite popular belief, the name “therapist” can be used by anyone because there is no professional license, governing body, or educational background needed to call oneself a “therapist.” Unlike other therapists, clinical psychologists have their doctorate degree and are licensed to practice psychology — that is, they have the training and board certification to diagnose and treat psychological problems, disorders, or abnormal behavior. Unlike most other therapists, I also use evidence-based, best practices according to the empirical (research) literature. In other words, I use methods that have been demonstrated to be effective for a given psychological problem, disorder, or abnormal behavior.
Some clinical psychologists are trained in conducting assessments and providing psychotherapy, and some are trained to conduct research. I am a clinical psychologist that does all three.
