In 1987, following a public outcry about its questionable medical practices, Staten Island's Willowbrook State School for people with intellectual disabilities closed its doors for good. Flat broke and almost finished with graduate school, Dan Tomasulo -- now a core faculty member at Columbia University's Spirituality Mind Body Institute -- was hired to relocate Willowbrook's most severely disabled inhabitants into a groundbreaking community-based group home. American Snake Pit is the story of the disregarded souls who ended up in Tomasulo's care; of the eccentric, resilient staff who helped make such a momentous success possible; and, most of all, of one man's persistent struggle to give voices to those who could not advocate for themselves.
