Charles G. Rosario Jiu Jitsu Instructor

This is a training environment full of incredibly talented martial artists, minus the attitude and swagger you find in so many places. Every single person in this gym is there to help each other get better. I love this place and these people.

Welcoming atmosphere, patient and knowedgable coaches, skilled and friendly students that challenge you in every way. Couldn't have found a better BJJ gym in Denver!

I am so grateful to have this gym in my life. I came in very nervous and tentative, but since that first day, I’ve been treated with utmost respect and support. The coaching staff truly cares about your development, your goals, and overall health. I’m in my late 30s and every gym membership just didn’t last, but this one did. I’ve lost weight, I’m starting to feel the potential of what my body can do, I’ve gained more confidence in myself, and I’m getting to know great people. It’s an honor to be a part of this gym. I can’t recommend Dark Horse enough.
