​Early in her career Sarah served with a Lake District Mountain Rescue Team before stepping away from medicine to work as an Outward Bound Instructor, developing skills in remote environments. She returned to medicine to support British and Canadian Marines in the mountains of Northern Iraq following the First Gulf War. 
After equipping herself with a postgraduate qualification in prehospital medicine, she went on to support numerous overseas expeditions, many at high altitude, and provided medical care in refugee camp settings before eventually settling into UK General Practice with the Ministry of Defence.
Sarah is now the UK Defence Lead for the prevention and management of cold injury, with extensive experience treating both non-freezing cold injury (NFCI) and freezing cold injury (FCI or frostbite). She has treated hundreds of patients with cold injury, regularly collaborates with national and international scientists and clinicians, has published research on cold injury, and represents the UK in NATO environmental medicine forums.
Sarah is Chair of the International Frostbite Resource Group and Secretary of IFRG-UK and the NFCI Independent Senior Advisory Committee (NISAC).
