Coach Jason Crutchfield of FWC Berston in Flint, Michigan. Coach Jason met Claressa 'T-Rex' Shields when she was 11 years old and although he never thought he'd have a female boxer, he immediately saw her potential. Now, Claressa lives with Jason full time and he is as much her second father as he is her coach. Now after boxing for six years, Claressa will be representing the USA at the London 2012 Olympic Games. This will be the first Olympics to have a women's boxing event, and Claressa is the youngest contender.
