"The Speech And Stuttering Insitute" of Canda program?

"The Speech And Stuttering Insitute" of Canda program? Hi, I've come across the following TED video, and wondered whether anyone had similar success stories (or failure?) at said institute. [https://www.youtube.com/watch?v=CQrZgsPsiRA](https://www.youtube.com/watch?v=CQrZgsPsiRA) ​ their site: [https://www.speechandstuttering.com/services/stuttering/intensive-fluency-treatment-program/](https://www.speechandstuttering.com/services/stuttering/intensive-fluency-treatment-program/) ​ ​ Or maybe other places who propose a similar treatment method? doesn't have to be Canadian, as i'm not as well. ​ Thank you!
