Psychologist - A psychologist is a professional who does psychotherapy and has a doctorate degree (such as a Ph.D. or Psy.D.). Psy.D. programs tend to focus on clinical practice and result in the professional having thousands of hours of clinical experience before they enter practice. Ph.D. programs can focus on either clinical or research work, and the amount of clinical experience a professional will gain varies from program to program. Psychologists receive specific training in diagnosis, psychological assessment, a wide variety of psychotherapies, research and more.
