Anyone ever been in HCRI?

Anyone ever been in HCRI? Hollins Communication Research Institute (HCRI) is in Roanoake,Va and its where they do stuttering therapy and from watching the results the videos are pretty cool to see someone who stutters severely to not at all. I'm 23 and my parents want me to go. My stutter isnt too bad, I have some bad days and then some good days. Just wondering if anyone here went to HCRI and could give me an insight on what its like and if it really helps. Thanks!
