McGuire Grad here as well as recently becoming the Regional Director of Australia, New Zealand and Singapore. Since doing my first course it has been a life changing experience. I held of doing it for about 5 years thinking it's too good to be true as well, but ended up going ahead with it when I couldn't get a job and really thought of it as "last resort". And I tried EVERYTHING before that - speech therapy, hypnotist, speakeasy device, vitamin b12 and other crap. It's been about 5 years since my first course course and the programme is just as effective for me. It's not a cure obviously, but you learn techniques about how to manage your stutter as well as why, how, when, where and other skills that overall help you deal with stuttering and yes, overcome it.
