I'm sorry Art that this unprofessional behavior happened to you. Is this the IOP thing? Sorry if I have not followed your recent posts correctly (I did read the other thread from today).
I think it's a very good idea to shop around for other facilities as well -- I'm guessing there should be options in Dallas? And then I would take it as an exploration initially, instead of counting on one or another place without direct experience with them. Talk to a few, do assessments at a few, see what suits you best.
This thing reminds me a bit of the time when I was looking for therapy and initially had only vague ideas how to look. So I asked around, investigated a few options, applied, did intakes, followed their instructions... to eventually find that it was best for me to search for and contact the therapists themselves. I guess this is different for IOP as it's an organized group thing, but I would still suggest to try a few places if possible. Wish you better luck!
