I did hcri this January and it was a great experience. The only thing is they kind of brainwash you to speak differently. You will literally barely stutter or not stutter again if you do the program and follow it. The problem is they make you talk like a robot. I recommend it for the experience of meeting other people who stutter and to learn the techniques. And it will be up to you if you want to follow those techniques and if you feel comfortable. I am glad that I went and experienced it. Just know there is no official cure for stuttering. Just some techniques on to better it
