The word “counsel” quite literally means “advice”. A marriage counselor, therefore, is simply a person who provides advice. A marriage counselor specializes in providing advice that relates to marriage. Counselors do not have to be licensed. Therapists do. Therapists are more than just counselors, and do more than just offer advice. Depending on your state and the level of education the therapist has, he or she can use specialized methodologies, exercises, and applied techniques in practice. Although counselors may have professional skills and experience, using a licensed therapist guarantees qualification at a professional level, and they can apply a wider range of treatment models.
