Onyx jiujitsu is something special, a truly fulfilling group to be with. It's a bona fide honest, accepting, hard working, inspiring, supportive community. Onyx was recommend to me by a friend, and it's one of the best decisions I've made since moving to Colorado. The people. The rolls. The jokes. The cheers. True and empathetic leaders. You definitely find it here.

Can’t say enough good things about onyx, the atmosphere in the room is incredible. The coaches lead by example and push the team to improve. The people in the room make it a special place. I’m glad to have found onyx on my move to Denver.

I can’t say anything bad about Onyx Jiu Jitsu. I am visiting Colorado to visit friends and family for five weeks and needed a place to train. I had a list of 3-5 academies to go to, and Onyx was the first. I never made it to the other academies because I enjoyed training at Onyx so much. At my first class, I decided to sign up for a month, and Coach Isaiah was super nice and accommodating to my needs. Him and the Onyx family were very welcoming. The classes are a mixture of intense and fun which is what I was looking for. They’re not going to drill you where you feel this sport is life or death, but they aren’t going to be super easy on you either. It’s the perfect mix, and I HIGHLY recommend this academy if you’re looking to get increase BJJ skill sets. I even brought in my 12-year old step-son for a class, and I’ve never seen him behave and pay attention like he has in this class. He’s only done two classes before this one, and this is by far the best one for him. I wish we lived in the area for us to actually sign up and train here long term, because him and I would be going here on a daily basis. If you’re looking for an academy, look no further! Thanks for the hospitality and amazing training while I’ve been in town. If I’m ever back, this is where I’m going.

A little over a year ago I had three local Jiu-Jitsu gyms I planned on trying, to decide where I wanted to train. Onyx was my first stop, I never made it to the other two. Coach Isiah and the tribe made the best impression on me on the first day and every day since. Onyx is a safe and encouraging place to train for all walks of life. The culture of the gym is truly something special. If you've ever been interested in Jiu-Jitsu or are looking for a new gym, I recommend you come experience Onyx.
