One of the all time greats in action! This classic series of nine films together in one video shows Dr. Charles Van Riper of Western Michigan University working with an adult who stutters. Therapy was done in seven sessions - one week apart - a total of seven hours of therapy. The eighth tape covers a follow-up session one year later. The ninth tape is a 20-year follow up and discussion of the long-term effectiveness of this therapy with Barry Guitar, Ph.D.
