The atmosphere is welcoming, the training environment is great, and the gym is always clean. Whether you're brand new or experienced, this is a fantastic place to train.

5 Stars - Fantastic for Kids!…read more We absolutely love this jujitsu studio! The instructors have the perfect balance of being strict yet incredibly patient. They create focused, structured sessions that still manage to be a lot of fun for the kids. What I appreciate most is how much the kids actually learn through practice--not just going through the motions. Each class builds their skills, confidence, and discipline in a way that feels engaging and rewarding. If you're looking for a place where your child can grow, learn respect, and have a great time doing it, this is the place to be!

Everyone at Black Diamond is super nice and friendly and always willing to help new people. The…read moreguys are great with the women and make sure they are safe. I came from another gym in town that treated the women inappropriately and have been here for 4 years now and love it. Also the guy talking about the open mat was a miscommunication between the two of them, however open mat is open to any and all people in the city not just black diamond members. If you are new, I would recommend attending the classes for awhile before jumping into open mat. The classes are structured and monitored by the instructor.

I messaged Gary to see if it would be ok to stop by and he was very accommodating. There were plenty of people to train with from white belt to black belt and everybody was very friendly. I've been training for more than 10 years at various gyms and I've never felt more welcomed - that's a testament to the owner. He even taught us some details on a few techniques that will help us evolve our games. I would highly recommend this gym for Reno residents and out of towners trying to drop in to get some rolls in.

He doesn't just teach; he builds. Leaders. Fighters. Better humans. His coaching style works for newbies and old dogs like me. The vibe is humble but hungry. The talent runs deep -- from fresh white belts to killers on the comp scene. Everyone lifts each other up. Huge plus: mats and gym are extremely clean. Max runs a world-class room with zero ego and full intensity. You show up, you work, you grow. Respect. Discipline. No shortcuts. Renzo Gracie Reno -- get after it.

They are not welcoming of neurodivergent children, they don't have training or education regarding what is appropriate for certain age groups, and they have poor communication skills.

If you're looking for top-tier Jiu Jitsu instruction in an incredibly positive and motivating…read moreenvironment, this gym is the place to be! The level of detail in the instruction is amazing--every technique is broken down in a way that makes sense, whether you're brand new to BJJ or a seasoned competitor looking to refine your game. The coaches are brothers who quite literally grew up on the mats, and their passion and work ethic show in every class. They create an environment where everyone pushes each other to improve, and you can feel the sense of community from the moment you step in. What makes this gym even more special is its deep roots in Jiu Jitsu history. Their father was one of the original Dirty Dozen, meaning their lineage and knowledge come straight from some of the first black belts in the U.S. You can tell that tradition and excellence are at the core of their teaching. Another huge plus is the variety of classes offered throughout the day, giving you plenty of opportunities to train no matter what your schedule looks like. Whether you're an early riser, prefer evening sessions, or need flexibility throughout the week, they make it easy to stay consistent with your training. If you're serious about improving your Jiu Jitsu in a gym with world-class instruction and a supportive family-like culture, this is the place to train.

There are usually two classes everyday, so it accommodates many schedules. All of the instructors are high knowledgeable and extremely helpful. They are also very good teachers. It's one thing to just be a good athlete and it's a totally different thing to be able to transfer your knowledge to someone else. They are very good at teaching techniques and actually demonstrating them. Another great part of this gym is the other students. There's a wide variety of skill levels and body types. They are all willing to work with you and give you pointers. No egos, but a lot of high level competitors are training in the gym. I would say if you have any interest in Jiu Jitsu to just come in and watch a class. If you like what you see they'll let you try a class or two. I'm sure you'll find it's an awesome place to train, just like I have.

It's one of the only Olympic style taekwondo schools in northern Nevada and their curriculum reflects it. Practices focus on belt level forms, kicks, sparring, and self defense. The community here is incredibly welcoming and a great place for kids to learn discipline, stay active, and make friends! First Taekwondo actively participates in northern and southern California tournaments and consistently places gold. Master Tanner has practice Taekwondo for over 30 years. He's passionate about his work and really cares for the kids and adults. He's also the coach for Nevada Taekwondo which is UNR's team. He has a team of black belts that teach as well, together they keep the classes unique and interesting so classes stay fresh. It's a fun and competitive environment and I can't recommend it more!
