What Our Students Say
Hear from our community about how training at our academy has impacted their lives.
James Bradford
"Kaiju BJJ has been the best experience I've had compared to any other gym. It's beginner friendly and has flexible class times to accommodate to any busy schedule. There is a true sense of community that makes training engaging, educational, and humbling. I would highly recommend Kaiju to anyone wanting to start Martial Arts in general, as the benefits extend far beyond just learning chokes and different combinations. The gym's cleanliness is top tier and the variety of classes make learning fun."
Ben Droege
"Great BJJ gym and super welcoming to all skill levels. The owner Aaron, alongside his coaching staff do a phenomenal job at cultivating a positive culture that encourages respectful sportsmanship and growing their students fundamental understanding of techniques. As a broke college student, I appreciate how accessible the pricing is, especially compared to other options in the area. I also feel that the hygiene standard for the gym is definitely worth mentioning; in addition to thorough disinfecting of mats after every training session, the staff do a great job of protecting the students by enforcing a strict no training policy if you're suspected of having afflictions like Ringworm, Herpes Simplex, Impetigo, and Staph/MRSA. No disease under the sun is taken lightly at Kaiju. 10/10 Gym, would train here again."
Matthew Moore
"To say that Kaiju BJJ is great is an understatement! Background: my four-year old has minor physical issues that affect his balance. His physical therapist recommended some exercises to build strength. Having wrestled myself when I was younger, I knew that grappling of some kind would be a great thing for him. Enter Kaiju BJJ! My family found this academy after TWO friends recommended. They described Coach Aaron and the studio as being extremely welcoming, patient, supportive, and structured. And they were absolutely right! My son and family are warmly welcomed by Coach Aaron every time. He makes a point to get to know every student personally and so that he can determine the right amount of instruction for them. My four-year old is in a class with five and six-year olds. There is a lot of physical and mental development that happens between those ages. But Coach Aaron is able to curate the instruction for each student so that is challenging but still accessible. My son really enjoys the classes, has a smile on his face when he is there, and his physical movements and balance have improved in only a few short months! We are so glad we found this community and feel grateful to have Kaiju BJJ in Yolo County!"

"As a brown belt with extensive experience in Brazilian Jiu-Jitsu along with extensive experience at other academies, I can confidently say this academy deserves 5 stars. The cleanliness of the facility is impeccable, contrary to what a previous one-star review mentioned. That review seems more like the frustration of a parent than an honest critique. Being a father myself, I understand it’s difficult for parents to be patient when their child isn’t performing well. But you need to trust the process. Writing a Google review with such outrageous claims such as contracting herpes is not only dishonest, but a true reflection of your character. I hope your son finds a better role model. Brazilian Jiu-Jitsu is not easy. You don’t get awarded participation trophies for showing up. Sometimes you’re held back to develop more. Sometimes you’re pushed forward before you’re ready to help step your game up. Aaron and his sons are exceptional instructors who are both patient and passionate about their craft. A purple belt is qualified to give fantastic instruction to anyone starting their journey, and even to practitioners who are 2-5 years experienced. Keep in mind, Aaron’s son is a Ralph Gracie black belt. You’re in good hands here. They truly care about the development of each student, offering detailed guidance and ensuring the atmosphere is welcoming and supportive for everyone. If you’re looking for top-notch instruction and a clean, respectful environment, this is the place to be in Davis, Ca."
