Peter Bradley is a man who has a lot to say when it comes to supporting people with stammers - and it's certainly worth listening to.
The Co Tyrone man has ended up as an NI Fire and Rescue Service crew commander but it has been a path fraught with setbacks, learning and a relentlessly positive outlook.
He has co-founded Belfast Stammer Support, an informal peer network aimed at bringing together people who stammer so they can share experiences and inspire.
