Stuttering is a communication challenge that causes the flow of speech to be broken up by repetitions, prolongations, or abnormal stoppages of sounds and syllables. It is estimated that over 300,000 Canadians are unable to order their favourite food, express their feelings or say what they want because of their speech. 

For more information about stuttering and how ISTAR can help:

The Institute for Stuttering Treatment and Research (ISTAR) is a self-funded institute of the University of Alberta's Faculty of Rehabilitation Medicine. We offer specialized treatment to children, teens and adults who stutter. In addition, we conduct research into stuttering, offer advanced professional training for speech-language pathology students and clinicians, and promote public awareness of stuttering and its treatment.
