Campus A sober companion or sober coach is an addiction treatment professional who provides one-on-one assistance to newly recovering drug addicts and alcoholics. The therapeutic goal is to help the patient maintain sufficient abstinence from alcohol and drugs to establish healthy routines outside of a residential treatment facility. The sober coach is a direct descendant of the Alcoholics Anonymous "sponsor," the only real difference being that the sober coaching is done for payment while a sponsor works for free as the practice of the 12th step, carrying the message of recovery.
