Jessamine "Jessa" Khan was born on October 8, 2001, in Corpus Christi, Texas, into a family shaped by constant movement. Her father's career as a Navy officer meant that stability came not from geography but from the values and disciplines the family carried across each posting. Those early years produced a natural athlete — Khan competed in ballet, soccer, karate, and tee-ball, with soccer emerging as her most serious competitive outlet during that period.

Khan's martial arts journey began with karate at age 6, a discipline that took hold quickly. When a family relocation to Hawaii cut off access to instruction, she didn't step away from martial arts — she pivoted. In January 2010, she joined O2 Martial Arts in Hawaii under the Onzuka Brothers and Shane Agena, beginning her Brazilian Jiu-Jitsu training at age 8.

The connection to grappling was immediate. Recognizing the value of a complete ground game, Khan integrated judo and wrestling into her training — not as standalone pursuits, but as tools to sharpen her jiu-jitsu. That multi-disciplinary foundation, built so early in her development, would become a defining feature of her competitive identity.

A Journey Shaped by Movement

Jessa Khan's climb through the belt ranks unfolded across multiple states and under multiple coaches, each chapter shaped by the rhythms of military family life. The Onzuka Brothers and Shane Agena at O2 Martial Arts awarded her yellow belt in Hawaii, where her BJJ story began. A relocation to New Hampshire brought her under Kevin Watson at KWBJJ, where she earned her orange belt. A subsequent move to Virginia placed her with Gustavo Machado, who awarded her green belt.

By age 12, Khan had already set her sights on a professional BJJ career — a striking clarity of purpose for an athlete who had spent her formative years moving from base to base. That conviction gave direction to what could otherwise have been a fragmented training history.

The AOJ Chapter

The defining turn came when Khan arrived at Art of Jiu-Jitsu (AOJ) in Costa Mesa, California, entering the academy as an orange belt. Under Guilherme Mendes, her talent found both structure and visibility. Her aggressive, forward-pressing style aligned naturally with AOJ's technical methodology, and her progression accelerated sharply. Guilherme Mendes awarded Khan her blue, purple, brown, and black belts — her entire upper-belt journey completed under a single coach.

The black belt ceremony took place on October 6, 2020, two days before her 19th birthday, making Khan one of the youngest recipients of the rank in high-level competitive BJJ.

Technical Identity

Jessa Khan's competition game is built on relentless aggression and forward pressure — a style that translates across weight classes and rule sets and has made her one of the most feared athletes in the Peso Galo division (48.5 kg / 107 lbs). Trained within the technical framework of Guilherme Mendes at Art of Jiu-Jitsu, Khan pairs sharp offensive instincts with positional discipline, consistently dictating pace and forcing opponents into reactive situations.

Juvenile and Colored Belt Dominance

Her juvenile career set the tone early. Khan claimed gold at the IBJJF World Championship and IBJJF Pan Championship in both 2017 and 2018, adding a European Open title in 2017 — a sweep of the sport's most prestigious juvenile stages that marked her as a generational prospect.

The purple belt division in 2019 produced one of the most dominant single-year performances the colored belt ranks have seen. Khan captured gold at the 2019 IBJJF World Championship, the 2019 IBJJF Pan Championship, the 2019 IBJJF European Open, and the UAEJJF Abu Dhabi World Pro — a quadruple title run that removed any doubt about her trajectory. Moving to brown belt, she added the 2020 IBJJF European Open title before receiving her black belt later that year.

Black Belt Results

At the black belt level, Khan has continued to perform at the sport's highest tier. She reached the podium at the IBJJF World Championship in 2021, claimed the top spot at the 2023 IBJJF World Championship, and won gold at the 2022 IBJJF Pan Championship — results that confirm what her colored belt run had long suggested. The reputation she built at AOJ has been fully realized on the international stage, where she remains one of the most dangerous competitors in her division.
