My friend was a very good amateur and he was friends with Ricardo Williams and Marshall Martinez and got caught up in that mess and did some time, which pretty much ended his pro career. He was the s&c guy for Ivan Najera. He's a good trainer, very good. If I had a son that wanted to box, I would move to San Antonio so my friend could train him. He had Gregory 'Goyo' Morales which is why Morales got signed to GBP, but Goyo ditched him and what happened happened.
His fighters are all good body punchers, especially with the hook to the liver. The right hand to the body, left hook to the head is a signature combination.
