GRPL HAUS JIU JITSU - Lone Tree

These guys are a classy group of instructors that keep focused on the details that count and do a phenomenal job with the kids they teach. They help the kids build confidence, toughness, strength, technique, speed, situational awareness, judgment, leadership and most important or all respect and character! We’re fans and so are our two boys aged 3 & 5. They’re having a blast! 2 Big Thumbs Up

We have been so happy to find Grpl Haus for our boys! They love attending classes and have participated in a few tournaments as well. The coaches are incredible. They combine discipline with skill and bring in aspects from outside the gym as well. For example, the coaches applaud and give praise for achievements at school or milestones hit for personal goals. This gym has become an extension to our family where we have found new friends and a safe place for our boys to follow their passion with jiu jitsu.

I’m not sure I can say enough good things about GRPL HAUS and its staff. They are simply wonderful! Our son started GRPL HAUS in Summer 2024. He has since attended 3+ practices per week, and he loves it. He goes happily and without complaint, and he comes home with more confidence, more self-defense skills, and life lessons. Coach Trey teaches life lessons after every class - it truly is fantastic to hear him educating the kids about ethics, positive leadership, and building trust and community. Coach Gonzo and Coach Drew (co-owner) teach the students applicable skills. They always keep the classes fun and informative. They work on body strength, they work on Jiu Jitsu technique, and they insist on safety and hygiene. Meanwhile, Rachel D. is quietly the heartbeat of the gym. She treats the kids like her own. She keeps the systems running, and she takes a ton of pride in how her gym operates. I highly recommend sending your children to this gym. They will be in great hands.

What more could you want from a jiu-jitsu gym than GRPL Haus’ motto: Work hard and be nice. Our kid started at a different gym, but everything changed at her first tournament. Her opponent was coached on the mat by Coach Trey, and my husband and I immediately knew we wanted our daughter learning from someone like him—someone who so clearly cares about the personal growth, confidence, and well-being of the kids he coaches. Now, she is. GRPL Haus is a true gem for helping kids develop hard work, physical and mental strength, self-defense skills, grit, and meaningful human connection. The coaches, along with Rachel, have intentionally built a community rooted in respect, kindness, and excellence—one where kids are supported as athletes and as people. Every kid would be lucky to be experience this. Bonus points: GRPL Haus is building an incredible group of girl jiu-jitsu athletes alongside an equally amazing group of boys. Seeing girls represented in nearly equal numbers speaks volumes about the culture they’ve created.

We met Coach Trey in early 2024 when we first signed our son up for jiu jitsu at another gym. We were bummed when Coach Trey left to open his own gym a couple months later but figured we’d stay with the gym we were at since it was closer to our home. However, after Trey had left we noticed pretty quickly the decline in the quality of the classes, my son was no longer looking forward to practices and the customer service and energy was leaving much to be desired so we followed him to GRPL HAUS. I might be driving a little further but it has been worth every extra minute in the car to watch my son (6 y/o) THRIVE in his jiu jitsu abilities, leadership skills, and confidence. Coach Trey has a way with kids that is both nurturing and strengthening and I am SO grateful to him and his team for their efforts, friendship, and the positive/emboldening influences they possess and teach my children.
