About

A highly reliable and versatile Air Diver and inland diving supervisor with 20 years of international experience in underwater construction, inspection, survey, and search & recovery operations. Over a distinguished 24-year career in the British Army’s Royal Engineers, I progressed from a heating and plumbing engineer to Army Diver, Diving Supervisor, and ultimately served as a Senior Military Diving Instructor and Lead Diving Supervisor at the Defence Diving School. Since transitioning from the military to the commercial sector, I have successfully adapted and broadened my expertise, working with leading diving contractors on a variety of complex projects inland and offshore. Known for being a dependable team player who performs effectively under pressure and consistently delivers high-quality outcomes in demanding environments.
