A marriage therapist is a special type of counselor that helps couples who are about to become married, or who are experiencing problems in their marriage. A marriage therapist is similar to a relationship therapist, except that marriage therapists only deal with clients who are already married or engaged. These therapists work extensively with the members of couples on an individual basis and in group settings. Marriage therapists are often represented in movies and television shows to help make the plot of a film or show more interesting. In fact, the proportion of marriage therapists represented on TV and the big screen is well over the real-life proportion of marriage therapists present in the real world. Sometimes a marriage therapist is a psychologist, but sometimes she or he is not. A marriage therapist may also be called a marriage counselor.
