Generally, the program is filmed and guests appear in studio, but in 2006 the Dr. Phil House began as an occasional series. McGraw and his production staff invite guests to a special house wired with numerous cameras and microphones. There, his staff monitors the conversations of the guests he is trying to help, and intervenes when necessary in order to prevent physical violence. McGraw also provides on-the-spot advice and counseling to the "house guests." McGraw's wife Robin sits in the studio audience for almost every show and, at the end of the show, she walks off the set with him.
