First tournament as Onyx Grappling, it went exceptionally well! As a collective, our team took 3rd place for Best Academy and 3rd place Overall.
The hard work, dedication, motivation, and growth shown through all of our competitors is impressive and something to be proud of!🏆

Proud of every one of our students.
It’s not just about the podium or the color of a medal. It’s about the hard work, dedication, discipline, and consistency they show every single day on the mats.
The growth we see in these kids goes far beyond competition. Confidence, resilience, and teamwork... that’s the real victory. 🖤🥋

More than just a team, we’re a family built through hard work, trust, and the bonds made on the mat.
Tonight we had a “sweet good bye” celebration for Gemma and Giulio after kids sparring class as they prepare to move this week.
We will miss having their family with us in the academy.
Once an Onyx family, always an Onyx family! 🖤
