NEW ERA Jiu Jitsu - Northglenn, Colorado

Professor Matt and the New Era Team are phenomenal! The Facility is wonderful and always clean! The community from the parents to the kids are truly one of a kind.

My son has been in the "lil jellies" program for a few months and he is loving it. He's excited to go to Jiu-Jitsu every day and even wakes up almost daily and asks "is today a Jiu-Jitsu day" It has also helped his focus and patience tremendously!

Thank you Professor Matt and the rest of the New Era family!

New Era Jiu Jitsu and Professor Matt Sierra

If you're looking for a premier Brazilian Jiu Jitsu experience in Colorado, look no further than New Era Jiu Jitsu under the exceptional guidance of Professor Matt Sierra. Our family has had the privilege of training with Matt for several years, and we cannot recommend him and his gym highly enough.

Our journey with New Era Jiu Jitsu began when our son started training under Professor Sierra at the tender age of 5. Over the course of seven transformative years, we witnessed our son grow not only in his martial arts skills but also in his confidence, discipline, and respect for others. Professor Matt's passion for teaching and his innate ability to connect with children are truly unparalleled. He has an extraordinary gift for making every child feel valued and capable, fostering an environment where they can thrive both on and off the mats.

As a family, we embraced the Jiu Jitsu lifestyle together. I (the dad) trained alongside my son, and my nine-year-old daughter also joined the New Era Jiu Jitsu family, training with Matt for three years. Through every class and every roll, Matt's dedication to his students shone brightly. His mentorship extended beyond teaching techniques; he played a crucial role in shaping our children's characters and instilling in them a strong sense of perseverance and integrity.

Living far from our family, New Era Jiu Jitsu became our home away from home. Matt and his team created a sense of community and belonging that went beyond a typical gym experience. The camaraderie and support we found at New Era Jiu Jitsu were instrumental in our lives, and leaving this extended family was one of the hardest parts of moving away from Colorado.

Professor Matt Sierra's commitment to his students is unwavering. His passion for Jiu Jitsu and his genuine care for each individual's growth are evident in every class he teaches. The culture of respect, hard work, and mutual support that he has built at New Era Jiu Jitsu is truly exceptional. If you are seeking a place where your family can grow, learn, and feel like part of a close-knit community, New Era Jiu Jitsu is the perfect choice. Our family's experience with Matt Sierra and his gym has been nothing short of life-changing, and we will always cherish the memories and friendships we made there.

I have known Professor Matt for 3 years, his knowledge and instruction are world class. He is an amazing father to his kids so the kids classes here are phenomenal. The school has plenty of mat space, impeccably clean bathrooms, a changing room, and cubbies to keep your stuff organized. If you are looking for a place to train, learn a martial art, or just get in shape, this is the best place. It's not just about getting amazing instruction, but about having a great culture and group of people to train with, this is the best place for all of the above. When you go in, tell them Logan sent you!

Fantastic place to train! Prof. Matt is one of the best jiu jitsu black belts in the state. I can't say enough about new era. Clean, friendly and great jiu jitsu. You won't be disappointed,

I had enrolled my son at New Era back in February. Our walking in was a bit of an accident, but it proved to be extremely beneficial. This school has not only gi training but no gi days. My son is only 5, but I’m glad they have the variation in training. Professor Matt and Coach Randy have a great way with these kids. They have a bit of fun, talk about important things for kids, and learn jiu jitsu. I could say more positive things, especially about the drive this location has to train legitimate practitioners, but the fact is if your loooking for a place for your child, this is a great choice.

New Era BJJ is one heck of a place. They have been so welcoming every time I visit, and everything is top notch.

The instruction is great, they break things down in a really easy to understand way so you can replicate their movements. On top of that, the place is immaculate, from the front door to the bathrooms and changing rooms, and of course their mat is spotless.

All the upper belts are fun rolls, I like their patience the best. So much technical work going on it's great to experience.

A+ totally recommend to everybody
