Career
In 2002, O'Bee was suspended for a year after testing at the 2001 US championship showed an elevated testosterone-to-epitestosterone ratio. O'Bee said the positive drug test "resulted from a special training regimen recommended by his coach, which involved dietary supplements and exercise."
O'Bee was fired by the Bissell team on July 31, 2009 for a doping violation. On October 7, 2010, the United States Anti-Agency handed O'Bee a lifetime ban for EPO usage.
All results he obtained after October 3, 2005 were vacated.
