Green Oaks is in North Dallas. In the old days (1985-1986), I think they used to send people on to Timberlawn if they needed "more" treatment. Green Oaks is part of HCA, http://http://www.greenoakspsych.com/. Back in the 80s there were so many hospitals with lawn and oaks in the name that it was downright ridiculous. Ironically Timberlawn was right next to "Grove Hill Cemetary". Irony, huh? Can you tell I have grown quite cynical?
Castle, you guys had another name for Chair and Room Therapy at CEDU but I cannot remember what it was. Basically no communication with anyone of any kind.
We had several variants. One was bans, which prevented us from communicating with specific students or specific groups of students. Then there were things such as booths and living rooms, and the most severe was the full-time.
Not sure what the details are regarding chair and room therapy, but room therapy also sounds similar (in name at least) to quiet rooms, which are used in many lock-up and psychiatric facilities. (Similar to a "time out") Patients who were "going off" were locked in such rooms to quiet down.
Dallas in general had a lot of oak and lawn things. Green Oaks facility, West Oaks facility, Timberlawn, Oak Lawn (gay neighborhood), South Oak Cliff (da hood. spent quite a lot of time there.

)
And other tree related things. I heard, much to my disappointment, that forest lane no longer has a forest. sad.
