Many of you know John's name from his book Redefining Stuttering: What the Struggle to Speak is Really About.  He also authored the famous Stuttering Hexagon diagram and article. John explains why he prefers the concept of "Holding Back" over stuttering.  He was one of the original 15 people who participated in the National Stuttering Project- now known as the National Stuttering Association.  John participated in Toastmasters for several years before leading public speaking workshops in the Bay Area of California. I have learned a lot from John since first meeting him in 1997.  I think he helps SLPs think outside the box of mainstream treatment methods for stuttering.(Search his book title on on the internet and the 600+ page book is available for free on PDF).
