Any stutters who have attended the HCRI stuttering program in Virginia: what is your experience/success?

Any stutters who have attended the HCRI stuttering program in Virginia: what is your experience/success? Hello everyone, Long time stutterer here. Recently, my friend, who has had a very mild stutter all of her life, went to this program in Virginia and came back stutter-free. I talked about it with my therapist and she agreed that the program is very strong there. Apparently, HCRI consists of 14 days of rigorous speech therapy. The statistics show that the success rate is very high. Has anybody been to/had a friend who attended this program? Feel free to share your stories. Naturally, I'm a bit skeptical on the whole program in general. However, I'm strongly considering it. EDIT: The link for HCRI is http://www.stuttering.org.
