Andrew Becroft once had such a bad stutter that a teacher told him the three fields he could never work in were the law, the church and education.
Forty years on, he has worked in all three, and on July 1 he will become the country's seventh Children's Commissioner.
Mr Becroft, now 58, has been Principal Youth Court Judge for 15 years. He is an active member of the Karori Baptist Church and chairs the Tertiary Students Christian Fellowship.
But he has never forgotten the stutter that helped him to understand many young offenders with disabilities, and is patron of the Speech-language Therapists Association and the Speak Easy Association which supports people with speech impediments.
"Most of the serious young offenders are really struggling with neurodisability disorders including fetal alcohol syndrome, traumatic brain injury, autism spectrum disorder, dyslexia and communication disorders," he said.
