Therapist are good whether to treat stutter or not. They give you the opportunity to speak your emotions on a safety enviroment. In that subject she is a good choice. But don´t rely exclusively on her solving your stuttering. Chance´s are she don´t know how and probably won´t do it. Believe in yourself and your own observations. After all you know better about you that anyone. Keep a diary, write down when you stutter, lookout for clues. In time you will identify a clear patron. You will recognize your own belief system that has supported your stutter behaviour all this years. When you do that you will be one step closer.
