Mr Tim Beacon

CEO of Medical Aid International

Mr Beacon has spent 13 years in the Orthopaedic Medical Devices industry, focusing on Trauma, spinal surgery and joint replacement. His journey into healthcare has been an inspirational and unconventional one. He initially trained as an Operating Department Practitioner and subsequently became an Assistant Training Co-ordinator for the NW Thames Health Authority. During that time, Mr Beacon set up an outdoors adventure training company, running personal development courses, predominantly for healthcare staff, these received approval from Royal Colleges and were included as modules on degree courses, with one filmed as part of an ITV series on the John Radcliffe hospital, Oxford.

During his career, Mr Beacon has been a University healthcare lecturer and a civilian lecturer on the UK Special Forces Patrol Medical Course. He is the only civilian to have ever completed this course, and this came in particularly useful when running Primary Trauma Foundation courses in Africa. Mr Beacon has a post-graduate diploma in Travel Health at Glasgow Medical School and has written a book called “The Gap Year Handbook: An Essential Guide to Adventure Travel”. He has also completed and spoken on the ‘Anaesthesia for Developing Countries’ Course run by the University of Oxford.
