We battled so much and we learned so much from each other. He learned straight from the fountain which was me and my brother. If you are in Colorado and want to check out one of the best Jiu-Jitsu schools and one of the best Jiu-Jitsu instructors in the entire country, you are in the right place. Check out Dark Horse BJJ and you are going to find the best place in Colorado for Jiu-Jitsu and I sign below. See you guys on the mat. Oss!"

You Would Be Crazy Not To Train At Dark Horse BJJ!

"I consider Matt a great training partner and friend and I would highly recommend him as a teacher.  He has a wealth of technical knowledge and more than that, he is a good person who represents the martial arts way of life.  If you are in his area, you would be crazy not to train at Dark Horse BJJ!"

Excellent instruction and an unbeatable value

"Dark Horse BJJ provides top-notch instruction from two world class Brazilian Jiu-Jitsu Black Belts. Professors Jubera and Dudderar have cultivated an atmosphere that provides for safe and detailed instruction, a strong sense of camaraderie and healthy competition. Coach Tamarchenko’s Thai boxing class is an awesome introduction to Muay Thai and a great way for students of other striking martial arts to move to the next level. Overall, Dark Horse offers excellent instruction and is an unbeatable value for anyone wanting to learn self defense, get in great shape and become a well rounded fighter."

An awesome place to train

"Dark Horse BJJ is an awesome place to train, and it has been a privilege to have been a student here from the beginning. I don't think there's another place in this country you can get as much one on one time with black belts as a novice, and there aren't many where you can get such strong, solid instruction in the fundamentals. Professors Dudderar and Jubera are so easy going about training with the lower ranks that it's easy to forget that they're international competitors who have trained under and gone up against some of the best in the world. If you're in the area and have been sitting on the fence about whether or not to give it a try - take the plunge. You can't let an opportunity to start your jiu jitsu journey at such an amazing place go to waste!"
