Avi Fishoff did help us, but it was hard for my husband to completely commit to the hashkafa behind Twisted Parenting. I was doing it, but it’s not as effective if both parents aren’t completely committed to it. ‘Speaker’ put me in touch with Avi, and it definitely helped me to get a more accurate view of the situation, and a derech for dealing with my son. Speaker can tell you more, but I think Avi only meets with a group of maybe 5-8 couples at a time(?). This is after meeting with each couple separately for many hours, until the couple has fully embraced the hashkafa behind TP.
Here in Israel, I found it almost impossible to get help when I was in crisis. There are a limited number of organizations that deal with this, and they are quite dispersed and not always available. It took a tremendous amount of time with us running after them and putting pressure before anyone got involved. Perhaps now, which is about 15 months after my son fell apart, they are actively involved in trying to help him.
May you have much siyata d’shmaya! (Because that’s REALLY what you need).
