i was lucky enough to live in edmonton growing up and my parents put me through their program. i was far too young at the time to remember anything specific, but from what my parents tell me when i first started i was one of the most severe cases they had seen. by the end of the program, my fluency was one of the most improved cases they had considering where i started from. apparently they used to (not sure if they still do) use video tapes of me as an example of severe stuttering for speech pathology courses.
