I did. I can only recommend it! I had a severe stutter with tremendous anxiety because of it. Now I'm more comfortable in most speaking situations and stuttering is no longer a major worry in my life, although I do have the occasional blocks once and a while (but not as bad or as profound as it used to be) Although don't expect it to "cure" you, they teach you how to have control over your speech, and you'll have to practice that daily if you want it to last. The major advantage of the McGuire Programme over any other similar programs is that it has a huge support network of coaches that will assist you whenever you need them. And the community around the program is very supportive and friendly. (who are all stutters themselves, not some college graduates who learned about stuttering in textbooks) Although it works better for some people than others, its success rate is better than any other programs and therapies out there. So I do recommend you give it a shot.
