Serediak was a three-time selection to both the All-America Second Team (2003, 2005 and 2006) and the All-Ivy First Team (2003, 2004, 2006) for men's squash. At the end of a freshman season in which he was 12-6 from primarily the No. 1 position, Serediak was ranked 12th in the country — the highest final ranking by any Big Red men's squash player to date. He went on to compete in the Professional Squash Association, where he ranked as high as 106th in the world as of February 2015.
