it was 20 years ago for me so keep that in mind. I don't remember much of anything (perks of being a stutterer I think maybe) but I know it was a game changer in terms of getting the chip off my shoulder I had about it. I wouldn't feel as in control or as comfortable with having a stutter - never would have done Drama at uni, so can only speak from own experience but it helped me. It's a cliche but it's exactly like AA in that being run by people who have suffered is good therapy. Everyone involved knows how you feel so they really can help process it, as fluent people with stutters themselves. 'fall seven times, stand up eight.' - that's the mindset, and they help structure habits so you really can be more fluent. I was lucky in my Mum went to lengths to help with my stutter that I took for granted at the time, if you can afford to do the program then I'd say go for it, but be fearless, listen to what they say, and commit to the exercises. I think nearly all of us don't have a complete handle on it and until you are around others who stutter it's easy to let that cause isolation, so for the perspective alone it's worth doing.
