Never had to enroll my own kid in something like that, thank God, but in early 2021 or so my wife called fifty-two psychiatrists before we found one (i) that was within 50 miles (ii) that had the subspecialty we needed and (iii) was taking patients. I imagine if you think you’ve found the “right” one of these places, you are loath to move on to the next one.
I think I’ll pass on watching that documentary, however. I’ve seen quite enough.
