Namoff grew up in Rockford, Illinois, where he emerged as a soccer standout at Boylan High School.

He played college soccer at Bradley University from 1997 to 2000, where he was a first-team All-Missouri Valley Conference selection in 1999 and 2000, and scored a total of 32 goals and 17 assists while with the team.

However, a change of coaches in the offseason brought Ray Hudson to the team, and Namoff's time was significantly curtailed.

In 2003, Namoff began seeing more playing time for United at right back, appearing in 22 games and registering one assist.

[1] Along with teammates Bobby Boswell, Brian Carroll, and Joshua Gros, Namoff made his first (and, to date, only) international appearance for the United States men's national soccer team on January 20, 2007, against Denmark.
