ABOUT US

Founded by Marcellus and Stephanie Casey, our gym operates as part of Championship Greatness, a nonprofit dedicated to empowering athletes, coaches, and families through faith, fitness, and mentorship.

We offer boxing and strength training for adults and youth, providing expert coaching in a welcoming, high-energy environment. Whether you're looking for personal training, group boxing classes, or open gym sessions, our space is designed for all skill levels—from beginners to seasoned athletes.

But what makes us different? Every paid workout directly supports our free competitive youth boxing program. Through this program, kids in Kansas City receive top-tier boxing training, mentorship, and personal development opportunities at no cost to them. We believe that boxing isn’t just about physical strength—it’s a tool for building confidence, discipline, and resilience in and out of the ring.

By training with us, you’re not just investing in your own fitness—you’re helping the next generation of champions. Join us and be part of something bigger!
