@3xteens I haven't dealt with them personally, but having read this and previously linked threads I personally wouldn't touch them with a bargepole.
My DD is in recovery now thanks to meds (private psychiatrist), equine assisted therapy followed by CBT-like therapy, and time.
However I know that lots of autistic teens also suffer from anxiety so I'd want an autism specialist and certainly not this bunch of non / hardly qualified people.
Please before using them at least read the threads and listen to the radio 4 programme about them before committing yourself.
