  • "NJ Ronin is place that made me feel welcomed immediately."

    The instructors are amazing and are always encouraging everyone to ask questions. Definitely a place I can go to so that I can relieve any stress I had from the day. If you are hesitant about starting something new, whether it is Jiu Jitsu, striking, wrestling, or judo, definitely come in to watch. Danny is awesome and will let you try out what you want to learn so you can have a feel for it. I’ve been there for almost 6 months and I wish I did it way earlier!!!

  • An excellent place with outstanding people and fantastic instruction"

    NJ Ronin is an excellent place to not only learn martial arts but be apart of something greater than yourself. Everyone at NJ Ronin is very friendly, has no ego and is more than willing to help out as much as learn and grow themselves. If you're on the fence about where to train or even get a good workout just stop in and get a feel for yourself. It is an excellent place with outstanding people and fantastic instruction. I would recommend to anyone at any age looking to better themselves.

  • Getting back into BJJ after being out for over a decade, could have been a stressful experience... but I am extremely lucky to have found a martial arts academy that was so welcoming and accommodating as NJ Ronin is. Danny's facility and members made me feel at home after just a few classes. Everyone is dedicated to improving one's self on and off the mats. The facility itself is clean, very spacious, and allows for recovery (saunas), as well as a gym area with a plethora of equipment. If you are on the fence about joining, take the leap of faith and walk on the mats...you'll thank yourself and be hooked

  • This place has grown immensely since it started. From upgrading the fitness section with some of the best lifting and training gear around, to the recovery room complete with two different kind of saunas and a massage chair, the place is legit. Highly recommend stopping by and checking it out.

  • I’ve been training at NJ Ronin for a few months and I wish I had started sooner. The building is split into two parts, a nice open mat space for sparring, grappling, drills, classes, etc. The other half is a spacious and fully stocked gym with all of the equipment that you could ever need. There’s also a very nice sauna room to aid with recovery. They offer a great variety of classes and there is plenty of open mat time as well. Most importantly, the people here are great and I’m glad that I get to train with them regularly. Everyone here is humble and shows up ready to learn and better themselves. Last but not least, the owner is a super nice guy and has built something truly worthwhile here. Come in and train with us!

  • My 5 yr old and 7 yr old have been attending classes at NJ Ronin for a year and a half! They LOVE it! They have learned so much and I am really impressed! Coach Danny is amazing with the kids! Highly recommend!

  • After taking my first class I was hooked! Not only has NJ Ronin helped me get back into shape but it’s helped build my confidence. I’ve never done any form of martial arts prior to this but Danny made me feel welcomed and supported.

  • This has been a fantastic experience for all 3 of my kids. My boys were all new to the sport this past year. Coach Danny and his team have done an incredible job onboarding them into a new discipline while fostering a new sense of accomplishment and self-confidence in each of them. NJ Ronin feels more like a community...a family ...than just a dojo. Side benefit, the kids come out dripping in sweat 3 days a week! I cannot more highly recommend NJ Ronin. Incredible value for the $$

    Jason Forest
  • NJ Ronin had an incredible atmosphere! Great coaching and great training partners! A must if you live in the area, can’t recommend them enough!
