I work for Independent Speech and Language Therapy Services Ltd (ISLTS) in Norwich.

I am a highly experienced, caring and dedicated Speech and Language Therapist with over 28 years’ experience in the NHS and independent sector supporting children and adults with a wide range of speech, language and communication needs.

I specialise in assessing and treating stammering (stuttering) and cluttering across all ages, helping children, teenagers and adults communicate with greater confidence and ease. I have completed specialist training in evidence-based therapies, including Lidcombe, Palin PCI and Camperdown, and regularly attend National Stammering CEN study days to keep my practice up to date. My previous research at the University of Suffolk, led to publications on childhood stuttering in peer-reviewed journals and presentations at international conferences.

I take a holistic, compassionate approach, providing personalised therapy that helps people achieve their communication goals.
