I would like to know how the Seed got placed in direct lineage with Phoenix house in that chart. That isn't right!
Probably the AA roots. Phoenix was closely tied in with Synanon when they attempted to "take New York" with the therapeutic community model.
One early connection Maia missed was Hyde School. Hyde definitely also has AA roots. Officially begun in 1966, but Gauld possibly tried it earlier at New Hampton in the late 50's, and definitely at Berwick Academy prior to '62. Others did not share his "vision" so he started his own school. In the earliest days, students were required to acknowledge a "higher power" and to observe religious services. He stopped making them go to church, but the lingo is still peppered with AA phrases and terminology. That and est/business buzz words about "unique potential," "moral compasses," and "destiny."
