William D. Parry, CCC-SLP - Background
Further information about William D. Parry, CCC-SLP:
Bill Parry is a licensed speech-language pathologist and former trial lawyer. He received his law degree from the University of Pennsylvania Law School, where he was an Editor of the Law Review. He earned his Master's Degree in Speech, Language and Hearing Science from Temple University. He is now ASHA-certified and licensed in Pennsylvania and several other states. He practices Speech-Language Pathology in the Philadelphia area and worldwide by video conferencing (depending on location and subject to applicable law).
After struggling most of his life with a severe stuttering problem, Parry became frustrated with existing theories and therapies and began his own research and experimentation. This resulted in his "Valsalva Hypothesis" (published in the Journal of Fluency Disorders in December 1985) and a therapeutic approach called "Valsalva Control," which dramatically improved his fluency. This enabled him to become a successful trial lawyer in Philadelphia, representing injured persons and their families. He has been listed in the Bar Register of Preeminent Lawyers, Who's Who in America and Who's Who in American Law.
Parry founded the Philadelphia Area Chapter of the National Stuttering Association in 1985 and led its support group meetings for more than 15 years. He served for six years on the Board of Directors of the National Stuttering Association and as Chair of its Advocacy Committee. He has has appeared on TV and radio talk shows and, in 1987, received the "Spirit of Philadelphia Award" from WCAU-TV Channel 10 News. He has given workshops and presentations on the Valsalva Hypothesis locally, at NSA conventions, at the Third International Convention for People Who Stutter in 1992, at the World Congress of People Who Stutter, in 1995 in Sweden, in 2011 at the International Stuttering Association's 9th World Congress for People Who Stutter, in Buenos Aires, Argentina, at the ISA' 10th World Congress in Lunteren, Netherlands, at the British Stammering Association National Conferences in 2012 and 2014, and elsewhere. He has been invited to speak at the ISA's 2019 World Congress in Iceland.
A preliminary edition of his book, Understanding and Controlling Stuttering, first appeared in 1992. The Completed Edition was published in 1994 and the Second Edition was published in 2000, and was reprinted five times. It has been published in Korean by the South Korean Speech and Hearing Association, and it is also being published in Russian. It has been the NSA's best-selling book and one of the most popular books about stuttering on Amazon.com. The Revised and Expanded Third Edition was published in 2013 and is now available from the NSA and Amazon.com.
Since 2010, Parry has been developing the Worldwide Valsalva Stuttering Therapy Program - a comprehensive new therapy to reduce stuttering blocks and promote easy, natural-sounding speech - with the participation of dozens of persons who stutter from all over the world.
