At the heart of our gym is Sean McCully, a true pioneer in the world of mixed martial arts. With a remarkable career spanning 56 professional fights, Sean is a two-time World title holder and a four-time National title holder, who fought in every traditional weight class from 147 pounds all the way to heavyweight. His passion for martial arts and his dedication to perfecting his craft have made him a respected figure in the sport.

Sean's journey didn't stop at his success in the ring; he also played a pivotal role in shaping the current landscape of MMA as we know it. Alongside legends like Jason Parillo, his brother Justin McCully, and other notable figures, Sean founded the first-ever MMA gym in Southern California, a revolutionary step that set the stage for the sport's growth in the region and beyond. This groundbreaking gym became a hub for fighters and enthusiasts, establishing a community where the foundations of modern MMA training were built.

Today, Sean brings his years of experience, passion, and dedication to our gym here in Jacó, where he continues to inspire the next generation of fighters and martial arts enthusiasts. He’s joined by his son, Sean Jr., and daughter, Zoe, who both live and train at the gym, carrying on the family legacy. Together, they represent the spirit of martial arts, blending tradition with innovation in every class they teach and every fight they face.

Our gym isn't just a place to train; it's a family. And our story is a testament to the McCully legacy in MMA—a journey that started in the ring and now lives on through every member who steps onto our mats.
