"Any time I am in town I come to train with Arnaldo and his team. He is a great teacher and his training room is full of high level and technical guys. The mats are always clean and the rolls 10/10"
"absolutely love the crew and vibe here. the sign up and cancellation process were the smoothest of any school I've ever visited. School has a laid back attitude with a bunch of absolute killers."
"I was visiting my mother her in Reseda, CA. From Atlanta, GA. Did a drive by and happened to stumble on Checkmat, Northridge. Went in met with head instructor Arnaldo Maidana, introduced myself and asked if I could train at his gym. He said of course. My visit here was good, even better having the privilege of training with a bunch of solid guys. Thank you for having me as your guest. Excellent Jiu-jitsu. Gi & Nogi"
