I specialise in working with teens who stutter but can point you in the right direction: - Michael Palin Centre for stammering - you can ask your GP to fund it for you - City Lit - run groups and courses - type "stammering therapy for adults NHS London" if you want NHS options - Redefining stammering - you can go on the ASLTIP website (association of speech and language therapist in independent practice) and search for stammering specialists in your area. Many will offer a free initial call so you can ask questions and decide if they're the right for you. Good luck with your search!
