Inside the Rise & Fall Of A 1970s Upper West Side Cult: GothamistAfter the raid, the pillagers returned to their seven-story co-op at 2643 Broadway. “We were prepared for them to invade,” says Paul Sprecher, a member of the Sullivan Institute for over a decade. “We had security down at the front door to make sure they would be duly chastised. I don’t remember, I think one guy showed up to complain and he was manhandled.” (According to a 1989 New York Magazine article, the complaining tenant was “beaten by more than a dozen members,” one of whom “broke four knuckles punching the young boy in the face.”) The paint splatter that started the ordeal is still visible today, on the brick wall just above the Metro Diner on 100th and Broadway. It is perhaps the last physical reminder of a psychotherapy cult—informally known as the “Sullivanians”—that once had 500 members living in three buildings on the Upper West Side.
