Mike Feil has spent more than 20 years on the mat. Most of his experience has come from scholastic and freestyle wrestling where he wrestled all year round in tournaments up and down the east coast with the biggest one being the National AAU Freestyle Wrestling Tournament in Michigan placing 4th in the nation.

After college, Mike was the wrestling coach at several different high schools until he found his new home with Brazilian Jiu-Jitsu. When he made the transition to Jiu-Jitsu he already had the stand up technique and "mat awareness" in his favor.

Mike is currently a first-degree black belt under Jay Goldberg (Black Belt) and Regis Lebre (Black Belt). Mike took the Bronze Medal in the 2009 Pan American Jiu-Jitsu Tournament in Carson, CA, and took the Gold at the 2009 NY International Tournament.
