Atom, Jiu-Jitsu & Science

“I’ve been doing bjj for over 3 years now and this is the best experience I’ve had yet. I have been out due too a foot injury for 4 months and my father had a herniated disc so he has also been out. We are both rehabbing and he excepts that we are injured. Coaches always invites me to class and I can not do everything but when I say no coaches do not push. They are very kind and skilled. They are good at instructing and alway make sure everyone understands. They make small adjustments to your form and technique so you are always learning. They are instructive but not rude to the students. The gym itself is a good space and everyone has enough room. They have a downstairs where you can put your belongings, change into your gear, and use the restroom. The people of the gym are kind and welcoming to new comers. They also help you learn as needed. As for the kids over the age of 12 they are usually put in the adults class and the adults help them learn and instruct them as they roll”

“5 Stars – Absolutely Incredible Gym If you’re looking for the best place to train Brazilian Jiu-Jitsu in the Newton or greater Boston area, look no further than ATOM Jiu-Jitsu & Science. This gym is next-level — a beautifully designed, ultra-clean facility with world-class instruction led by Professor Daniel Mola, a second-degree black belt under Demian Maia. Whether you’re a complete beginner or an experienced grappler, ATOM has something for everyone. The environment is welcoming, professional, and supportive. Classes are thoughtfully structured, and Professor Daniel’s teaching style is clear, technical, and detail-oriented — you can tell he’s not only an elite athlete but also a gifted coach and educator. The mat space is massive, featuring Zebra mats (top-of-the-line), wall padding, padded pillars, and incredible lighting — perfect for both training and filming content. The lobby/lounge area is clean and stylish, with leather seating, greenery, and a professional aesthetic that feels more like a premium wellness center than a typical gym. Every detail, from the layout to the atmosphere, has been designed with care. What makes ATOM truly special is the culture. You’ll find a respectful, positive, and ego-free training environment where everyone, regardless of age or skill level, is treated like family. It’s an amazing place to train, improve, and grow both physically and mentally. If you’re serious about learning jiu-jitsu or just want to start something new to challenge yourself, I highly recommend checking out ATOM Jiu-Jitsu & Science. You won’t find another gym like it.”

“Amazing gym and such a gift to the area. Dan is an dynamic instructor - I’ve trained at a couple different gyms and learned a huge amount in only a few months at Atom. He’s also built an awesome community; super welcoming no matter your level or goals. Different class times to accommodate every schedule. Definitely check out a class if you’ve ever considered trying jiu jitsu, I bet you’ll stick around!”

“Daniel was actually a professor at the first gym I started at many years ago. I had to drop in with some old teammates when we found out that he opened his own gym. He continues to deliver top-tier instruction. I especially appreciate his attention to detail and integration of kinesthetic concepts. His lineage and competitive background puts him a cut above the rest. He facilitates safe sparring with a high level of training intensity. This is an excellent gym to train at or drop into.”

“This is by far the best gym I have ever trained at. With nearly two years of total training experience and this being my third BJJ gym, I can confidently say Dan’s teaching and training methodology is truly exceptional. His structured approach ensures that techniques are thoroughly learned, often dedicating an entire week to specific positions like side control or mount. In contrast to other schools I’ve attended, which lacked organization in their instruction, this structured approach has significantly accelerated my learning. I earned my blue belt at my previous gym after 1.5 years of training. However, when I first started here, I questioned whether I truly deserved it. The level of talent at this gym is outstanding, and training with such skilled students has elevated my game far beyond my expectations. I cannot recommend this gym enough. It’s fun, safe, and fosters an incredible community. Whether you're just starting your journey or looking to advance your skills, this is the place to be. OSS!”
