Has anyone done or know anyone that has done the MPI2 Stuttering programme??

Has anyone done or know anyone that has done the MPI2 Stuttering programme?? Im a 33 year old male from the UK and came across the MPI2 Stuttering treatment not so long ago. Currently there is only one speech therapist in the UK that does this type of therapy but its more used in America. Is there anyone in this subreddit who has done the programme or knows of someone who has? I have spoke to the therapist and am most likely going to give this a go. The programme is based on scientific research and studies. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4610276/ Judging by the article, i think its worth a shot.
