“What makes a great bjj school? That question comes to mind when choosing a jujitsu school for yourself and for your kids. A good bjj school needs a highly qualified and competent instructor. And this is what makes Checkmat corona a great school for learning Brazilian Jiujitsu. Professor Jimmy is a highly decorated jiujitsuka who has won many competitions under his belt and is a very technical instructor.

The school in itself has that inviting ambience. As soon as you step in, you’d feel the camaraderie among students and that overwhelming feeling of being part of a much bigger Jiujitsu family. You can’t go wrong with this school. Professor Jimmy has helped me a lot in my techniques and has helped me gain much confidence in my abilities when it comes to groundwork. His knowledge of Jiujitsu and technical know-how is really an eye opener even for experienced grapplers.”

“There are plenty of places you can choose and I've been to a few over the past decade. What keeps me here is Professor Jimmy Tat. When you join Checkmat Corona family, you will get the personable care and attention given as one would from a protective older brother not just a instructor.

His personal experience gives him extraordinary perception to be patient and understanding to even the youngest members of his students. Even during the struggles of the pandemic- he has worked with me and my young girls to continue our training via zoom because of my concerns without any hesitation. He has taken many precautions to assure safety for everyone else as guidelines have eased up but still never hesitated to continue to indulge my concerns and requests.

Checkmat is just an all around wonderful school for families. I have learned a lot more about the intricacies of Jiu-jitsu in the time I've been here than I have anywhere else over the years combined. It's Prof. Jimmy that is experienced, knowledgeable, approachable, patient and overall a positive motivator. Again, there are many choices out there but for me and many others, this is where we choose to stay.”

“My son has been with Checkmat Corona, under Professor Jimmy Tat since 2017. We had moved from another gym and shortly after we made the transition, my son's jiu-jitsu skills and knowledge quickly improved.

With that said, my son has done very well at BJJ tournaments throughout the last four years, successfully winning many tournaments. We are grateful to have Professor Jimmy always there coaching our son as he is an excellent coach! In addition the gym is family oriented, friendly and competitive at the same time where everyone pushes one another in a positive way.”
