When it comes to finding the right Jiu Jitsu academy, students look for more than just mats and classes, they’re looking for expert instruction, a welcoming community, and a place where they can grow both on and off the mat. At High Altitude Martial Arts (HAMA), we’ve spent years building exactly that: a world-class Jiu Jitsu academy right here in Denver.
Here’s why our students, ranging from beginners to seasoned competitors, call us the best Jiu Jitsu academy in the city.
Experienced Coaches with Real-World Expertise
HAMA is led by a team of instructors who bring decades of training, competition, and coaching experience. Our coaches don’t just teach techniques, they live and breathe martial arts.
- Cody Donovan (UFC veteran, BJJ black belt under Amal Easton) leads with a wealth of experience in high-level combat sports and a passion for developing students at every stage.
- Avery Brooks brings elite competition strategy and mentorship for those chasing medals.
This depth of expertise ensures that whether you’re training for self-defense, fitness, or competition, you’re learning from some of the best in Colorado.
A Welcoming, Family-Oriented Community
At HAMA, we believe Jiu Jitsu is for everyone. Our student base spans children as young as 4 years old, busy professionals, first responders, and serious competitors. What makes us special is the family atmosphere, we’re not just training partners, we’re a team.
Parents love the way their kids gain confidence, discipline, and lifelong friendships. Adults appreciate the supportive environment where beginners feel welcome and advanced practitioners are challenged. Step into our academy and you’ll immediately feel the difference: smiles, encouragement, and energy from a community that lifts each other up.
Programs for Every Age and Goal
We know that no two students are alike, which is why we’ve built a program that serves everyone:
- Youth Jiu Jitsu: Teaching kids confidence, respect, and resilience through martial arts.
- Adult Jiu Jitsu: Classes for all levels—from complete beginners to advanced black belts.
- Competition Training: Specialized coaching and drilling for athletes preparing for tournaments.
- Grappling for MMA: MMA programs to build a complete martial arts skillset.
This variety means every student can find their place on the mats and progress at their own pace.

Proven Competition Success
HAMA isn’t just about training in the gym, we test our skills on the competition mats, too. Our athletes regularly compete at local, regional, and national tournaments, bringing home medals and making a name for Denver Jiu Jitsu.
But what makes us proudest isn’t just the wins—it’s the way our students compete with respect, humility, and sportsmanship. The lessons learned in training translate directly to success in life, on and off the podium.
World-Class Facility and Atmosphere
Located in the Denver/Aurora area, High Altitude Martial Arts offers a clean, safe, and welcoming training environment. Our academy is designed for growth: spacious mat areas, top-notch equipment, and a schedule packed with classes to fit any lifestyle.
Parents can watch their kids train in comfort, and adult students know they’re stepping into a professional, high-energy space designed for success.
A Legacy of Excellence in Martial Arts
HAMA has deep roots in Denver’s martial arts scene. Our coaches and founder, Nate Marquardt, have trained with some of the best in the world, bringing that knowledge home to Colorado. Students here aren’t just learning moves—they’re carrying on a tradition of discipline, respect, and resilience.
