Born on October 22, 1952, in Recife, Brazil, Romero Cavalcanti relocated to Rio de Janeiro at a young age — a move that would set the course of his life in martial arts. It was there that he first encountered Brazilian Jiu-Jitsu, beginning his training under coach Jaildo Gomes. That early instruction gave Cavalcanti a foundational grounding in the art that would anchor his entire career. He later deepened his development by training at an affiliate of Carlson Gracie's academy, sharpening his technical skills and expanding his understanding of the Gracie system.

The defining chapter of Cavalcanti's formative years came when he joined the academy of Rolls Gracie, widely regarded as one of the most gifted and innovative practitioners in BJJ history. The relationship that developed between the two transcended the typical athlete-coach dynamic — Rolls Gracie became a fatherly figure to Cavalcanti, and the influence of that bond would shape his philosophy as an instructor for decades to come.

In 1982, Cavalcanti received his black belt from Rolls Gracie, placing him among the final group of black belts that Rolls promoted before his tragic death in a hang gliding accident later that same year. The six men Rolls promoted before his passing were Mauricio Gomes, Marcio Stambowsky, Romero Cavalcanti, Nicin Azulay, Paulo Conde, and Mario Claudio Tallarico. This cohort represents a historically significant moment in BJJ lineage, and Cavalcanti's inclusion among them reflects the trust and respect Rolls placed in his development. The values instilled during those years — technical precision, dedication, and deep reverence for the art — became hallmarks of Cavalcanti's own teaching identity.

Following the death of Rolls Gracie in 1982, Cavalcanti continued his evolution as a practitioner by training under Rickson Gracie, ensuring his connection to the highest levels of Gracie Jiu-Jitsu remained unbroken. This period reinforced the technical and philosophical foundation that Rolls had helped build, carrying that lineage forward with integrity.

Cavalcanti channeled that accumulated knowledge into establishing the Jacaré Jiu-Jitsu Academy. The gym reflected everything he had absorbed from his mentors — a commitment to instructional excellence, technical depth, and the cultivation of serious practitioners. The academy served as both a respected training ground in its own right and the seedbed for broader organizational ambitions that would leave a lasting mark on the global BJJ community.

In 1993, Cavalcanti co-founded Alliance, a team that would grow into one of the most accomplished and influential Brazilian Jiu-Jitsu organizations in the world. Alliance distinguished itself through a culture of high-level competition, rigorous instruction, and an unwavering commitment to producing technically sound practitioners at every level of the sport.

In 1995, Cavalcanti relocated to the United States with a clear mission: to expand the Alliance network beyond Brazil and bring world-class BJJ instruction to American practitioners. He initially settled in Miami before establishing his base in Atlanta, Georgia, where he built one of the most respected Alliance affiliates in the country. Under his stewardship, the Atlanta operation became known for producing elite competitors and upholding the high instructional standards that Alliance had come to represent — a pivotal contribution to the broader international growth of Brazilian Jiu-Jitsu as a discipline.

Romero Cavalcanti's reputation as an instructor stands among the most enduring in the BJJ world. In 2009, that reputation received formal recognition when he received the "On The Mat" Instructor of the Year award — an acknowledgment of his sustained teaching excellence and his lasting impact on the practitioners who have trained under him throughout his career.

Also in 2009, Cavalcanti faced a significant personal challenge when he was hospitalized in Atlanta due to a serious illness. He made a full recovery and returned to leading his academy, demonstrating the same resilience and dedication to the art that has defined his career from its earliest days.

Known throughout the global BJJ community by his nickname "Jacaré" — the Portuguese word for alligator — Cavalcanti has built a legacy that spans decades, continents, and generations of practitioners. His name carries a weight of instructional credibility that few in the sport can match, and his contributions as a coach, organizer, and ambassador for Brazilian Jiu-Jitsu have left an indelible mark on the art.
