Sarah Warley


Sarah is the Founder of The Key Clinic, the first practice to bring together multiple cutting edge, drug-free treatments under one roof to help improve people’s lives.


“The existing model of mental and physical health care treatment is increasingly outdated, waiting until someone becomes sick and then medicating. Similarly in education, we prop children up with extra tuition instead of finding out why they are finding things difficult. By treating the root causes of difficulties, these exciting new approaches will allow us to redefine our own futures, academically, mentally and physically, without reliance on medications.”


Sarah has a BA and MA in Experimental Psychology from Oxford University. Following the birth of her four children, she was struck by the increase in childhood learning and behavioural difficulties and how little practical knowledge and help there was on offer to help overcome these problems. She went on to complete post graduate training as a Neurophysiological Psychologist at the Institute of Neurophysiological Psychology (INPP) in Chester and also qualified as an Auditory Integration Therapist, targeting the root causes of many learning and behavioural difficulties. Sarah is also a fully qualified Walsh Institute Practitioner, specialising in identifying and treating the biochemical imbalances which underpin emotional and behavioural problems, such as depression, anxiety and ADHD. She is also a qualified Bioflex LLLT practitioner, a technology which helps recover functioning by boosting cell repair and replication.


Having lived in the US, Japan, Singapore, the French Alps and the UK, she brings a breadth of experience regarding different evidence based approaches adopted in different countries. Sarah continues to research and train in the latest game-changing methods for helping unlock one’s full potential.
