Two SLPs does not mean anything. That is purely anecdotal and has little research. If you look up e Blank Stuttering Center which is extremely evidence based has done more for people who stutter than hard work. They have severa peer reviewed papers published. Their work is quite literally going global proving its not just the place that works but the manual program itself works. Rhetoric such as yours that “worked” for you does not work for almost anyone. Moreover, you only worked on blocks? So you dedicated a massive amount of time to one of the 3 types of stuttering. How do you plan to work on the other types of stuttering?
