We have had our son in therapy on and off for the past few years. He is currently with a new therapist and she seems to be having a good impact. He is 9 years old. I would say the biggest thing is the right fit. If you start with one and it doesn’t feel right, find another. Also, interview them beforehand without your son to get a feel for if they are the right person to handle the issues he is facing. Hope that helps! Good luck!
