Q: What is the difference between a counselor, a psychologist, and a psychiatrist? A: A person who provides psychotherapy services can be any of these professionals â or even a social worker or a psychiatric nurse. The main difference between these types of people is their training and educational background. A psychiatrist is a doctor who has attended medical school and done a residency in psychiatry.
