Julius Park

Born in Seoul, South Korea, Julius Park relocated to the United States at just one year old, eventually becoming one of the most influential figures in American Brazilian Jiu-Jitsu. His first exposure to martial arts came in first grade, though he set it aside before returning to Tae Kwon Do in middle school. The turning point arrived when he discovered VHS recordings of Royce Gracie competing in the earliest UFC events — footage that ignited a fascination with Brazilian Jiu-Jitsu that would define the rest of his life.

Determined to train, Park sought out Renzo Gracie's first academy, but the demands of the commute made consistent attendance impractical. Rather than step away from grappling altogether, he channeled that drive into high school wrestling — building a foundational command of body mechanics and competitive positioning that would pay dividends once he reached the BJJ mat.

First Steps on the Mat

Formal BJJ training became available to Park in 1998 when he enrolled at Cornell University, where Will Kabat-Zinn — a blue belt affiliated with Boston Brazilian Jiu-Jitsu — was teaching classes. Recognizing the limits of that setting, Park transitioned to the Renzo Gracie Academy, where he immersed himself in a structured program under Renzo Gracie himself.

Building Through the Ranks

By 1999, Park had earned his blue belt under Renzo and taken on the responsibility of running Cornell's unofficial BJJ club — introducing the art to fellow students while continuing to sharpen his own skills. Before he departed Cornell and returned to Maryland, Renzo Gracie awarded him his purple belt in recognition of his growth and contributions to the university's grappling community.

Earning the Black Belt

Back in Maryland, Park joined Lloyd Irvin's Team, where training under Lloyd Irvin elevated his game significantly. That high-caliber, competition-driven environment pushed him through his brown belt and, in 2013, to his black belt — completing a journey that had begun over a decade earlier with a VHS tape and an unfulfilled trip to a Manhattan academy.

In 2005, Julius Park founded Crazy 88 in Baltimore, Maryland, driven initially by the practical need to train more frequently and with a deeper pool of partners. That personal solution to a training problem grew into one of the most respected grappling academies in the United States, distinguishing itself not just regionally but on the national competitive stage.

The academy's reputation rests on the caliber of competitors it produces. Athletes such as Tim Spriggs, Tye Murphy, and Devon Delbrugge emerged from Crazy 88 as elite grapplers of their generation, regularly medaling at prestigious national and international tournaments. The consistent output of high-level competitors from a single Baltimore-based gym stands as direct evidence of the environment Park built — one defined by organizational rigor, deliberate coaching, and an uncompromising standard of excellence.

Julius Park carries the nickname "The BJJ Scientist" — a moniker that captures his methodical, principle-driven approach to the sport. Rather than relying on talent identification or informal instruction, Park constructed Crazy 88 around a structured curriculum that teaches athletes to understand the mechanics and underlying logic of techniques, not simply repeat them.

This emphasis on why techniques work — the leverage, timing, and positional principles behind each movement — develops grapplers capable of adapting and problem-solving at the highest levels of competition. The emergence of multiple elite competitors from a single regional academy reflects this philosophy in action. The Crazy 88 model has come to represent a clear blueprint for how analytically rigorous coaching can accelerate athlete development and sustain competitive excellence over time.
