Tiedeman grew up in Santa Rosa, California and attended Montgomery High School.
He opted for baseball after leaving Montgomery, turning down a contract offer from the Atlanta Braves and accepting a scholarship at the University of Arizona, where he roomed with current Giants closing pitcher Mark Melancon.
Tiedeman rededicated himself to basketball, spent one season at Santa Rosa Junior College, and committed to Boise State as a sophomore.
In August 2010, Tiedeman signed with West-Brabant Giants, a club from Bergen op Zoom, Netherlands.
