- MSc Clinical Exercise Physiology student
I am the Co-Founder of DD Performance & Wellness. I started out as a personal trainer in 2008, helping people become stronger, healthier and more confident, and saw first-hand how movement can transform mindset, self-belief and quality of life.
During COVID I recognised that physical health doesn’t exist independently of mental health and behaviour, so I trained as a Mental Health Nurse and worked across acute, older people’s, alcohol and detox, forensic and liaison services. I am now completing an MSc in Clinical Exercise Physiology to bring movement, understanding and clinical knowledge together.
