Agreed, there is nothing fast about stuttering treatment. That's why the programme is a lifetime thing, not a once of course. As far as effectiveness - the intensive courses are extremely effective, literally everyone comes out with really strong control and use of techniques, think of it like a speech boot camp. Then the methodology is to continue practicing through the support groups and with your personal coach from the program. Then you would attend further courses / boot camps and get more and more proficient and the technique becomes automatic, as you can hear in the video from the director Denis and from the course instructors. As far as business model - sounds ominous from your post, but I know for a fact it's the opposite, where possible the directors of each region try and set up physical groups and run regular grad weekend and one day courses, which is absolutely free to us Graduates /members. In Australia we just had a great weekend event in Tasmania and prior to that in Singapore (where a lot of west coast people traveled to).
