A professional MMA competitor from 2000 until 2011, Reinhardt fought in the UFC and King of the Cage.
After compiling a 1-0 amateur record, Reinhardt won the SFC Submission Fighting Championships professional bantamweight title on 11/3/2000 defeating Arizona fighter Ray Duke.
He went on the following year to win the RSF Reality Submission Fighting Championships professional bantamweight title defeating WEC veteran Del Hawkins on 3/30/2001.
From there Reinhardt faced Japanese star Hideo Tokoro in the main event of ZST 9 in Tokyo, Japan.
This fight was changed to a grappling only match after Tokoro signed a contract the week prior to ZST 9, to face Royce Gracie in K-1: Premium 2005 Dynamite.
