Leo Sacco
"One of the most rewarding and enjoyable experiences of my life. Derek does an amazing job creating a community of like minded individuals that values hard work. and commitment. Derek and his other instructors are extremely knowledgeable and dedicated to helping others in their Jiu jitsu journey. My only regret is not walking through the doors of Heavy Mettle 5 years sooner!"
Braden Verge
"My daughter and I have absolutely loved every minute of our experience at Heavy Mettle Jiu Jitsu. From the moment we walked in, the environment has been welcoming, supportive, and empowering. The instructors are incredibly knowledgeable and patient, creating a space where both beginners and experienced practitioners can thrive. For my daughter, it’s been amazing to see her confidence grow with each class. The balance between learning self-defense and developing discipline has been exactly what we hoped for. The kids’ classes are engaging, fun, and challenging in all the right ways. As for me, it’s been an incredible opportunity to learn alongside her. The training pushes us to be better physically and mentally, and the sense of community here is unmatched. Everyone is dedicated to helping each other grow, both on and off the mats. We couldn’t recommend Heavy Mettle Jiu Jitsu more. It’s been such a positive experience for our family, and we’re excited for all that’s ahead!"
Patrick Smart
"I can’t recommend Heavy Mettle Jiu-Jitsu enough. I joined HMJJ a little over a month ago after training at another school for quite a while. From the moment I walked through the door I’ve been welcomed like a friend by everyone. Derek and his team of instructors are top notch, and have created a sense of community that’s apparent in every class. The atmosphere is one of consideration, encouragement and challenge, any egos are checked at the door, and training partners understand that we all start our training at the same place, all of which provide opportunity to develop skill and get a great workout. As someone who started training Jiu-Jitsu in their 50s, I’m confident that this sport isn’t just for younger practitioners, and if you’re just starting, you’ll wish you started sooner, but you’re never too old to begin. The academy schedule also offers multiple opportunities to train throughout the week, including Saturday and Sunday. If you’ve ever thought about getting a great workout in a welcoming environment with some great humans, I recommend giving Heavy Mettle Jiu-Jitsu a go, you’ll be glad you did."
Scot Bowers
"Really an awesome place to learn jiu-jitsu, get a great workout, and make friends for life. What I love most about Heavy Mettle is how everyone is treated with respect, we all take care of each other, and egos are left outside. The instructors are top notch - every one of them dedicated to helping the students learn and grow. None more than Derek Stevens, the owner, who teaches most of the classes. Derek's curriculum based approach to teaching is incredible. The classes are thoroughly planned months in advance with the flexibility to modify the instruction based on new information all the time. Derek introduces the material gradually week after week over the course of months, building on what was previously taught. This results in so much better understanding and retention. I have gained a much deeper understanding of many top and bottom positions in two years at Heavy Mettle Jiu-Jitsu Academy, than I did in five years at various other schools. Finally, maybe more important than anything else, Derek goes out of his way to maintain a very clean and hygienic facility. I feel super fortunate to have the opportunity to train at Heavy Mettle and look forward to doing so for a long time."
