Carol started stammering on her first day of school and has had many years of speech therapy. She has a more overt stammer which can be a clear indicator of stress and is often extremely wearing if she has a busy day interacting with others.

Dr Yincent Tse

Newcastle Hospitals NHS Foundation Trust, Newcastle

Yincent is a Children’s kidney consultant and Lead for Quality and Safety at the Great North Children’s Hospital in Newcastle. Son of first generation migrants, English was not his first language. He came to the UK aged 8 and adapting to a new language he started to stammer very noticeably. “My enduring memories of growing up was a total sense of helplessness and isolation, somehow during my adolescence coherent speech could only escape through sarcasm which must have been horrific for those around me.” He managed to get into medical school with kind words from admission tutors talking over him, ‘he can always be a pathologist if he can’t speak to patients.’ He has wide interests in quality improvement, equality, medical education and making animation to aid patient information.

Dr Lorraine Maher-Edwards - Mentoring Supervisor

Guy’s and St Thomas NHS Foundation Trust, London

Lorraine is a practitioner psychologist who works in the Rheumatology department of Guys Hospital in London; she also has a busy private practice. She has many years’ experience of working with people with a variety of long term physical and mental health conditions. Lorraine’s stammer can be unnoticeable to others and yet has been a challenge in particular in her work life. Lorraine’s relationship with her stammering has evolved throughout the years and she believes strongly that cultivating openness and acceptance of our vulnerabilities can allow for growth and change. Lorraine has mentored people who stammer working with the Employers Stammering Network and is now the mentoring supervisor for the NHS Stammering Network. She is also conducting research into the application of Acceptance and Commitment training (ACT) for self-advocacy in people who stammer (with Dr David Gillanders, Dr Ute Liersch & Sam Simpson).
