thoughts/experiences/results/advise for Camperdown Program (Australian based) or any other therapy programs for adults/adolescents who stutter. Hi, I'm a student speech pathologist. I'm just looking for some advise and info before I start a placement. I was wondering whether anyone has done the Camperdown program and what their experience was with it? Did you like it, did it help, why or why not? Also in general, what could the therapist have done/not done/ said to help you better during therapy?
