Mark has travelled widely even as a child, having been brought up on the island of Antigua in the West Indies then moving onto the Middle East and Saudi Arabia. Mark studied Geography at Middlesex University before he set off and joined Raleigh International. He was involved firstly as a venturer then joined the team full-time in the office doing just about every role imaginable, spending his weekends running selection weekends for participants and staff. Mark then set out into the field again on expeditions to Costa Rica and Northern Australia. In Australia he was fortunate enough to land a job running the logistics for a geological company and spent a blissful nine months working in the bush digging holes!

Returning to the UK he worked for a brief spell in an office but knew this was not for him. So he entered a Special Forces Regiment with the TA having completed numerous wet and windy treks in the Brecon Beacons. Mark was with the TA for just under three years many of the skills he learnt with the TA were easily transferable to the work he now does at Expedition Medicine; leadership, expedition skills, medical safety back-up, night navigation, practical skills and casualty management in remote areas.
