Tom only took up boxing at the age of 18 but is now one of Team GB's most decorated fighters and world number one at light-welter.
He lost out to Frankie Gavin in the Beijing squad but went on to establish himself as the best lightweight around on Gavin's move to the paid ranks.
In 2010 he won gold at the Commonwealth Games and silver at the Europeans, leading him to be named amateur boxer of the year.
He moved up to light-welterweight last year, winning another European silver medal, and in September became the first member of the GB Boxing squad to qualify for the Olympics when he beat Alexander Solyanikov to make the quarter finals of the World Championships in Baku.
He eventually went on to win a bronze medal but was disappointed with that performance and will be looking to go two better in London.
