Overview
About NJ Ronin
NJ Ronin is a Brazilian Jiu-Jitsu academy at 110 Grand Ave in Hackettstown, NJ, offering a broad training environment that reaches well beyond a single class format. The academy pairs Jiu Jitsu and Jiu jitsu school instruction with MMA / Boxing, Kickboxing school, Boxing Gym, Striking, Wrestling, and Judo, giving students a place to build a well-rounded game from the ground up. Its program lineup also includes Open mats, Training, Fitness, Physical Fitness Programme, Self Defence School, Martial arts school, and Recovery (Recovery Room), making it a practical choice for athletes who want to train, condition, and recover in one location. Families can also find Kids Jiu Jitsu and Striking, while those looking for individualized attention can explore Personal trainer and Women’s personal trainer options.
The coaching team features Danny Jantzen, Matt Nicolls, and Kelly Ryan, with brown belt instruction offered by Danny Jantzen and Kelly Ryan. That combination gives the academy a clear connection to active mat experience and a teaching approach rooted in direct technical development. For students, that means a setting where drilling, live work, and skill-building can be balanced with striking and wrestling cross-training, supporting both self-defense goals and competitive aspirations. The inclusion of Judo club and Wrestling school programming further strengthens the academy’s appeal for practitioners who want to sharpen takedowns, balance, and control as part of a complete martial arts foundation.
What helps NJ Ronin stand out in the local BJJ community is its mix of serious training and athlete-friendly amenities. The Recovery Room, Multiple Saunas, Massage Chair, and Open mats / free time on mats create a strong practical advantage for anyone training multiple days a week. Students can put in hard rounds, then use the recovery space to help stay consistent and keep their body ready for the next session. That kind of setup is especially valuable for beginners who are learning how to pace themselves, as well as experienced grapplers who want a place that supports long-term progress.
With its wide program range, hands-on coaching, and recovery-minded facility, NJ Ronin offers more than a standard martial arts school experience. It is built for people who want to improve in Jiu Jitsu while also exploring striking, wrestling, judo, boxing, and fitness under one roof. For local students in Hackettstown and nearby areas, the academy provides a flexible training path, useful amenities, and an environment designed to support steady development on and off the mats.

FAQ
Frequently Asked Questions
What kinds of classes and training programs does NJ Ronin offer?
NJ Ronin offers a broad training lineup that goes well beyond a traditional Brazilian Jiu-Jitsu room. Students can train Jiu Jitsu, MMA / Boxing, striking, wrestling, judo, kickboxing, self-defense, and fitness-focused classes, along with open mats for extra mat time. The academy also includes kids Jiu Jitsu and striking, personal training, women’s personal training, a boxing gym, a jiu jitsu school, a judo club, and a physical fitness programme. That variety makes it easier to find a path that matches your goals, whether you want to build confidence, improve conditioning, compete, or cross-train across multiple combat sports. If you want the current class mix or the best starting point for your experience level, checking directly with the academy is the best next step.
What are the class times and hours of operation?
The clearest way to confirm class times and hours at NJ Ronin is to check the academy’s website or contact the team directly, since schedules can change as programs are added or adjusted. With a training menu that includes Jiu Jitsu, wrestling, striking, boxing, judo, open mats, kids classes, and recovery-oriented amenities, the timetable is likely organized around multiple age groups and training goals. If you are planning your first visit, it is smart to ask which classes are best for beginners, whether open mats are available on the day you want to come in, and how the academy structures its weekly training blocks. That way, you can arrive prepared and choose the right session for your experience level.
How much does membership cost, and is there a trial class?
Membership pricing is best confirmed directly with NJ Ronin, since the most up-to-date rates and any introductory offers can change over time. A practical first step is to ask whether the academy offers a trial class, a day pass, or a short intro option so you can experience the training environment before committing. Because the school supports so many paths, including Jiu Jitsu, MMA / Boxing, striking, wrestling, judo, kids training, and personal training, pricing may vary depending on the program you choose. When you reach out, ask what is included in membership, whether open mats are part of the package, and whether recovery amenities such as the Recovery Room, multiple saunas, or the massage chair are accessible to members.
Is NJ Ronin beginner-friendly, and do I need martial arts experience to start?
NJ Ronin is a strong fit for beginners because its program mix includes Jiu Jitsu, self-defense, fitness, personal training, and kids classes alongside more advanced combat-sports options. That combination usually makes it easier for new students to start at a comfortable pace and grow into more technical training over time. If you have no prior experience, you can ask which class will give you the clearest introduction to movement, base, and basic positions before moving into live rounds or cross-training. The academy’s wide range of disciplines also helps beginners who want to improve general fitness first and then branch into grappling, striking, or wrestling as their confidence builds.
How do I book a trial class or schedule a visit to NJ Ronin?
The most direct way to book a trial class or schedule a visit is through the academy’s website at http://www.njronin.com/ or by reaching out to the team before you come in. When you contact them, ask which class is best for your experience level, what you should bring, and whether you should arrive a little early for your first visit. It is also helpful to confirm whether you want to see Jiu Jitsu, MMA / Boxing, striking, wrestling, judo, or the kids program, since NJ Ronin offers a wide range of training options. If you want to sample the facility beyond class time, ask about open mats and the Recovery Room so you can plan a visit that gives you the best sense of the academy.
