Good they should sue them. If you tell someone your kid is suicidal and ask them if their program can help their kid and they say yes knowing that it is just a hike in the woods led by people with no qualifications and with other kids with a wide variety of problems ranging from not getting along with their parents to heavy drug use and abusive families, then you should sue when your kid comes out dead.
Alldredge is responsible because they offered mental health services they were neither licensed nor qualified to offer to desperate parents.
In addition, Ayne or Alldredge may be a registered non-profit but I assure you that at 19K per kid and 5k a month after the first 3 months the operators certainly make a lot of money.
