Coach Darren is a very experienced and knowledgeable instructor of Brazilian Jiu-Jitsu and numerous other martial arts. Additionally, the Grappling Zone is a Great Facility to learn martial arts for all ages. Coach Darren and his facilities are the Best Colorado has to offer to anyone at any experience level. My daughter's and I thoroughly enjoy the family classes, and Coach D teaches and instructs at the perfect pace with excellent patience. I would highly recommend the Grappling Zone to any individuals or families in the State of Colorado looking to learn and/or master martial arts and their self-defense skills. I look forward to training at the new Grappling Zone location in Denver. Thank you, Coach Darren. Respectfully, D.G.

Great location. Great teacher. Everything is taught in a down to earth manner, meaning it's friendly for newcomers and advanced martial artists alike. From the moment you go in, you'll realize the good energy and vibes. Instructor Darren has been at it for a while, and you can tell due to his seasoned teaching style and patience.

Also, he is aware of what truly works, and what doesn't, and his knowledge of flow, and the steps to better technique are vast in scope. Real martial arts.

Darren has trained and worked with my son for several years, and he became a friend to my family. He's a great teacher and works well with people of all ages. Highly recommend his instruction for families, kids, and adults.
