Communication Therapy Institute is a private clinic that is dedicated to giving people who stutter the most effective, up to date treatment possible. Barbara Dahm CCC-SLP and Board Recognized Fluency Specialist founded CTI in 1987. Since then, over 2000 people who stutter of all ages have come to CTI to learn how to speak naturally, with greater ease and comfort. Through the years our therapy program has evolved from a more traditional fluency shaping approach to the present speech processing approach, Dynamic Stuttering Therapy. The basis for the development of our program derived from clinical observations and the feedback from clients confirming that specific changes in neurological processing have a direct cause and effect relationship with the production of normally fluent speech. Recent scientific studies are in agreement with our clinical observations and our perspective of the nature of stuttering.
