Walking on his hands? It's good that the school let that therapist go. Unfortunately, stuttering can be challenging to treat since not all therapies work for everyone. There's no one size fits all method. Speech therapy isn't a cure for stuttering but it a way to learn how to control your stuttering as best as you can.

You can check with ASHA, it's the American Speech and Hearing Association. They should be able to recommend someone in your area. I sure the Stuttering Foundation, the NSA, and FRIENDS, can also. The NSA have chapters all over the U.S. with support group meetings. That could be a great place for word-of-mouth recommendations.
