"I swam under Greg Colby from 2000-2004 and I remember my time being coached by him with very fond memories," wrote 2008 Olympic Silver Medalist and BHS grad, Emily Silver
. "He was extremely motivational and always energized. He cared not only for our team as a whole, but about each one of his swimmers individually. Because coach Colby came from a college swimming background, competing for the University of Wisconsin, he seemed to build his teams with the same mentality, always striving to push us to our limits in order to achieve our goals."
Greg now lives in Idaho and coaches for the College of Idaho.
