What Our Students Say

Peter Monaco
"Our experience at Busy BJJ has been absolutely fantastic! My 6- and 8-year-olds have been training here for several months, and the growth we’ve seen in both their skills and confidence is incredible. The coaches are outstanding — they’re patient, knowledgeable, and know exactly how to connect with kids. They strike the perfect balance between discipline and fun, creating an environment where my kids feel encouraged to challenge themselves while still having a great time. What I love most is how the gym emphasizes not just technique, but also respect, teamwork, and perseverance. I was concerned that it might be an atmosphere toxic masculinity and it's not at all. My kids are learning valuable life skills along with their jiu jitsu training, and they come home excited to show us what they’ve learned. The facility is clean, well-organized, and welcoming to families. The staff genuinely cares about each student’s progress, and it’s clear they’re passionate about what they do. If you’re looking for a supportive and professional environment where your kids can thrive, I can’t recommend Professor Mario and his team at Busy Bee enough!"
Calli Sarjeant
"I’ve trained with this team for the majority of my life and I’ve never been in a more positive community. The coaches and professors actually help you learn and make sure you know what you’re doing. I plan to recommend Busy BJJ to all my friends who show interest in martial arts."
Christa GIlstrap
"My son has been training here for about a year and half and we just love it! Professor Mario is fantastic and has the perfect blend between discipline and fun for the kids. We tried some other studios first and we knew from the first class this was the place for us."
