Mark Kamizaki

MatTime Brazilian Jiu Jitsu Coach

Mark and Frank Mark Kamizaki has been training in Brazilian Jiu Jitsu since 2007 and was awarded his Black Belt in 2016 by Cassio Werneck. Mark was born in Brazil but moved to the United States in 1997. Mark has been a loyal student and friend to Cassio. That said, Mark had to work even harder to earn his belts and has competed in the U.S. Open, the Pan Ams and the Jiu Jitsu World Championships. Cassio Werneck has never been one to hand out belts and everyone is forced to earn their belts and Mark is certainly one that earned. Mark is respected by his friends, peers and Cassio and is considered a highly technical Black Belt that is able to effectively handle opponents larger and stronger than he is. Mark is great with kids and we are happy to have him as both a Kids and Adult instructor.

Mark has a brother and sister that both train Jiu Jitsu and when he’s not on the Mat he’ll be furthering his career after receiving his B.S. in Kinesiology (Exercise Science focus) from Cal Stat University Sacramento.
