Union bjj mma has been a godsend for my family. Since the very first time we walked in their doors they have been nothing but welcoming and supportive. We originally started there with one child enrolled to give him an outlet as well as help build his confidence while learning discipline and self defense. Fast forward to now myself child, my husband and myself all take classes there. We absolutely love going there and are grateful to part of the Union family!

I couldn't be happier to have found Union’s MMA gym, and it's great to see my family getting involved as well. The coaches are incredibly friendly and make everyone feel at ease, whether you’re taking part in a class or just cheering on a loved one from the sidelines.

We discovered Union while attending the Gibbstown Memorial Day parade in 2025, where they were promoting their grand opening. Just a few weeks earlier, my boyfriend had mentioned wanting to find a new MMA gym since he had taken jiu-jitsu classes in another state, but the distance made it impractical for us now that we live in NJ. It felt like perfect timing to learn about this gym. Shortly after, my boyfriend signed up for a membership. A month later, our daughter joined too. The energy and enthusiasm from Chris and Ana, along with a warm, family-like atmosphere, inspired me to get my membership as soon as I recovered from having our second child. Even my sister has jumped on board for the dance fitness classes! I can’t rave enough about the dedication of the owners and coaches. With no prior experience in MMA, I initially had some hesitation about joining, as many do when trying something new. However, the support and encouragement from both the coaches and members have been invaluable, no matter their own skill levels. The membership costs are very reasonable, especially considering the wide range of skills you can learn. They offer an extensive selection of classes, including Jiu-Jitsu (both Gi & no Gi), Muay Thai, adult sparring, wrestling for kids, and now dance fitness classes. The gym has truly become our second home with how often we find ourselves there, and Union has evolved into a second family for us. We’re excited to watch our youngest grow up around everyone and one day join in the fun too. I encourage everyone to try a FREE class—you definitely won’t regret it!

We love the welcoming environment. The space is very clean and they offer high-quality training. They are always posting examples of what they do in some of their classes on social media. Love to see that. Go check it out!

The atmosphere is welcoming, disciplined, and motivating. You can clearly see the professionalism and passion in every class. It’s not just about learning Jiu-Jitsu or MMA, but also about building confidence, respect, and character. I highly recommend Union BJJ MMA to anyone looking for top-quality training and a strong community.
