"Graham has established himself as a high level sales professional, having managed large sales teams for multi-national organisations. Graham is based in Spain where he actively manages our growing portfolio as well as relationship management with several key players in Madrid & Barcelona. He is also responsible for Project Design & Development which covers all aspects of new property construction". (this is from a site of his company)
He also used to be an international referee. And a quite successful one. A lot of Champions League group stage matches and a quarter final in the UEFA Cup. He also took charge of the 2003 Super Cup, a kind of honorary job for a referee. He retired in the same year. Graham Barber was already 39 when he got his FIFA badge (he had been an international linesman before that) so his palmares isn't as long as most other top referees'.
