As the founder of SeaSure and regular all-year-round sea swimmer, Hannah brings the psychology to the courses.

She’s a fully qualified Counselling Psychologist, trained mindfulness teacher and has recently completed an MRes (Master of Research) in Clinical Research focusing on the wellbeing benefits of sea swimming

Hannah was keen to find ways to increase access to the sea for others so she was involved in setting up the Sea Swimming for Recovery courses based at the Recovery College in Brighton.
