I feel good recommending Pediatric Partners for Attention & Learning https://www.pp4al.com/information/contact if you are in Virginia.
I have had success getting help for my daughter who is open to help; but not for my son who was in his late teens and the developmental stage of “I don’t need help & Don’t tell me what to do” He quit therapy the moment he turned 18. At 23 he is revisiting on his own.
