Kelvin started shooting at the age of 12 while at Epsom College. He was a member of several Ashburton winning teams, was an Atheling in 1992, and subsequently captained the British Universities Rifle Team. This was followed by 6 years at Cambridge University where he won a Full Blue and studied medicine in his spare time.
Kelvin has been fortunate to have been selected for a number of international tours, representing England (USA 2008 & South Africa 2013), Great Britain (West Indies 2002, Canada 2011, 2012 & USA 2012, South Africa 2017) as well as travelling to Australia with GB to the World Championships in 2011. When not shooting, Kelvin enjoys playing golf and operating on people.
