Mike Sanda

Jeff Robertson

Mike started training in 2002 under Ricardo Ica Medina, and received his black belt from Bruce Shepherd in 2014. Mike loves to train jiu jitsu not only because it is a beautiful art , but when properly trained it can allow one to live a more confident and healthy life. Mike’s favorite techniques are defensive as he believes this is the true strength of the art - total defense through control.
