I agree with above posters about Ptach call them directly. I have known people that taught there they are sincere and direct. I know in flatbush chofetz chaim runs an arrowsmith program as part of their curriculum but am not sure whats involved and if its also for high school call them for more info. for more about the arrowsmith program

Additionally, while not fully familiar Darchei Torah in Far Rockaway is also known to have systems in place for learning disabled children and they have a bus to brooklyn and i know a boy who has succeeded and travels there everyday. However, as stated above I am not sure of what they offer so please call them.
