As a Clinical Hypnotherapist, I have worked with PWS. I think if you can get to the cause of your stutter, you can get to the cure. I have found the cause of 100% of my clients. Stuttering is caused by a traumatic event between the ages of 2-7. Any thing from a dog barking in a child's face, to a child seeing someone get shot! This is the spectrum that I have worked with. A lot of people can't remember what caused their stutter. But the subconcious remembers everything. So with Hypnotherapy it is easy to get to the traumatic event. Now that you understand what caused the stutter, now you can let it go from your mind and body. I am happy to answer any questions you may have. Thank you for your time.
