In the last several years she has parlayed her "sixth sense" into stardom with her hit TLC show, "Long Island Medium." There is rarely a moment when Theresa is not describing messages from spirits she says are looking to connect with their loved ones in the physical world. Even the "20/20" interview was interrupted when the deceased father of a cameraman apparently had a message to share.
