PAUL BOX-GRAINGER
Paul (aka Box) has a life-long involvement in hockey. Injury cut short his playing prowess, moving him onto umpiring through the Kent HUA and into the National League. He is best known for his unorthodox approach to umpiring, thinking ‘outside the Box’ and advocating the connection to players and coaches. This has led him to mentor and coach many of England’s most promising umpires.

HAMISH JAMSON
A ‘hockey-nut’ since he was 10, he eventually reached the dizzy heights of the local men’s 5th team. Having more talent with a whistle than a stick, he quickly found his calling, progressing through the ranks and into the National League as an umpire. With 165 international umpiring caps, he has officiated at 5 European Nations, 4 World Cups and the London Olympic Games in 2012. He is now a European and International Umpire Manager.
