Fenix Brazilian Jiu Jitsu

"I’m about two months into training at Fenix BJJ, and I’ve had an awesome experience so far. Coach Ethan does a great job breaking things down in a way that makes sense, even if you’re brand new. The vibe is super friendly — the adult members are welcoming, supportive, and make training fun. The gym is clean, well-run, and you can tell there’s a real focus on both growth and community. I’m really glad I chose Fenix to start my BJJ journey."

"I can’t say enough great things about Fenix! My 15-year-old son has been training here for about a year, and the experience has been incredible. Ron, Ethan, and the entire team have helped him build real confidence, and the personal growth we’ve seen has been amazing. The coaches are top-notch—skilled, dedicated, and committed to creating a respectful, ego-free environment where everyone feels welcome, from complete beginners to BJJ veterans. It’s truly a community where people help each other grow. Seeing our once reserved and quiet son thrive—not just in his BJJ skills, but in how he carries himself—has been such a gift. He loves it here, and so do we. We’re incredibly grateful to have found Fenix!"

"Fenix BJJ in Tewksbury is exactly what I’ve been looking for. I’ve tried multiple gyms in the area, but this is the first one that truly balances high-level competition with traditional Brazilian Jiu-Jitsu values. The coaching is incredible—detailed, structured, and focused on real growth. The training is tough but supportive, and everyone pushes each other to get better. The team atmosphere is awesome, with skilled training partners who are welcoming but also ready to roll hard. If you’re serious about BJJ and want to train in a place that’s both challenging and rooted in tradition, this is it. Highly recommend!"

"Fenix is a great gym. I joined along with my son who is the is in the kids classes twice a week and loves it. The instructors are very knowledgeable and it’s a very welcoming BJJ community. Learning Jiu Jitsu instills confidence in my son that will stay with him throughout his life. It is also a bonding experience for the both of us. I highly recommend for kids in adults alike."
