MY NAME IS

Owner & Head Instructor at

Nathan began training Brazilian Jiu Jitsu in 2009 and trained consistently for the last 16 years and was awarded his Black Belt in December of 2016.  He competed from white belt thru brown belt as well as on the big stage at 2 Fight To Win shows.  He always enjoyed giving back to those who came after him and that led to an opportunity to open an academy in April of 2017.  Over the last 8 years he has embraced being an instructor who truly cares about his students on and off the mats. 


Outside of the academy Nathan loves spending time with his 2 daughters as well as his 3 dogs while keeping up with family and friends.
