"They are kind and work wonderfully with kids! They make learning fun and challenging, teaching them new skills while encouraging teamwork with their peers.Thankful to have been recommended to this gym."
"I found this location upon recommendation and it has been the best choice. They are so welcoming and they work so well with all ages! Their women's self defense class is so helpful and caters to helping women in defensive situations along with doing target exercises for female body strengthening, specifically core. Their teaching for kids is so good and they work with kids of all energy levels and the kids enjoy it so much! I highly recommend giving Chekmat a try. All individuals can benefit from learning these techniques and Mayko and Karen are the best teachers overall."
"Professor Mayko and Professor Karen are extremely knowledgeable in the art of Brazilian Jiu-Jitsu. These two Professors not only have the knowledge, but the ability to teach in such a simple way, it makes it easy for their students to understand the techniques and the concepts of BJJ.

"Had 2 different stints travelling for work and Checkmat Phoenix was recommended by a friend. What a great recommendation! The culture here is second to none. It is a very welcoming environment and technical, high level jiu jitsu instruction. I can't recommend this place enough for anyone in the Valley or travelling through. You won't regret it!
