One of the most consistent scorers in Keene State history, Kathan capped his career as the third men's basketball All-American in school history. A three time All-LEC First Team Player, Kathan became the first KSC player to be named the LEC Rookie of the Year, and was a two-time LEC Player of the Year, winning the award as a sophomore in 2007 and again in 2009.
His sophomore season, Kathan and the Owls tied a school record with 25 wins, and defeated Rivier and Salem State to advance to the Sweet 16 of the NCAA Division III tournament. Kathan finished his career with his name all over the KSC record books, including leaving as the Owls' third all-time leading scorer, and finishing in the top 10 in shooting, three pointers, free throws, rebounding, while no one has started more games in school history than Kathan did.
His career did not end after Keene State, as Kathan signed professional contracts in England and Germany to play abroad.
