After graduates gain control over their own stutter many have a passion to help other people who stutter. They return to courses to assist in coaching roles and perhaps after appropriate training they become involved in instructing on courses. Other graduates leave the 4-day course 100% fluent and feel they are "cured".
However, because they don't practise the breathing and speaking technique or challenge their feared speaking situations, they continue to have problems. However, they can then return to a 4-day intensive refresher course for only a small daily fee, refresh their technique and get back on track.
