reat school with an awesome environment! The facility is clean, welcoming, and has a great atmosphere for both adults and kids. You can tell a lot of effort goes into making sure everyone feels comfortable and respected while they're training.<br><br>One thing I really appreciate is how seriously cleanliness and hygiene are taken. The mats and facility are kept extremely clean, and the overall attention to hygiene really stands out.<br><br>The environment is supportive, friendly, and encouraging. whether you're completely new to jiu-jitsu or have been training for a while this is Definitely a great place for families and anyone looking for a clean, positive, and professional school to train

Don't have enough good things to say about this gym! Coach Yim is not only a great coach who knows what he is talking about, but also very inviting and accomodating. Makes beginners feel very comfortable and runs a very clean gym. His sessions are fun with a lot of emphasis on live rounds, not just drilling the entire class.

Had a wonderful experience at Kokoro Jiu Jitsu. I attended the grand opening which was a great time. Coach Mike is a super nice person and a great instructor. He built a community full of solid people and a positive culture. The new gym is awesome and I can't wait to stop by for more classes soon! :))

I just joined Kokoro Jiu Jitsu last month and I love it. Michael Yim is one of my favorite coaches. I learned a lot of grapples and takedowns from him. I recommend everyone who is interested in Jiu Jitsu to check out this place.
