From the reviews
I feel incredibly fortunate that Mass BJJ The Valley is where I began my BJJ journey. I truly can’t imagine a more supportive and positive environment, and that’s a direct reflection of Ed’s leadership.
Had an awesome experience at this gym. I jumped into open mat Jiu-Jitsu and had some great rolls with everyone there. I grabbed some sweet swag gear before heading out. The coaches were amazing. They made everyone feel welcome from the moment we walked in.
My son absolutely loves Mass BJJ in Deven! Coach Ed and his team are fun, attentive, and encouraging. The classes are structured well to keep the various age levels engaged while learning a variety of techniques that they immediately put into practice. I highly recommend!

New to BJJ? Start at Mass BJJ The Valley
Mass BJJ The Valley comes up as a beginner-friendly gym — noted on their own site. If you've never rolled or set foot on a mat, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or flexible to start — you get in shape by training, not before it, and coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.
Your first BJJ class at Mass BJJ The Valley
Nervous about walking into a BJJ gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.
