Osvaldo Moizinho was born on August 18, 1986, in Rio de Janeiro, Brazil, and stepped onto the judo mat for the first time at age 8. That early exposure to grappling opened a door to a broader exploration of combat sports — over the following years he trained in luta livre esportiva, muay Thai, and boxing before finding his true home in Brazilian jiu-jitsu at age 16.

His first BJJ coach, André Terencio, guided Moizinho from his earliest days on the mats through his brown belt. When Terencio relocated to Chicago in 2008, Moizinho made a pivotal transition — joining Soul Fighters under founding members Rafael Barbosa, Leandro Escobar, Bruno Mendes, and Augusto Tanquinho. It was within that environment that he earned his black belt in 2011. Time spent training alongside Caio Terra further reinforced and refined his technical foundation during this formative period.

Just three months after receiving his black belt, Moizinho relocated to the United States to pursue a full-time career as a professional athlete — a decisive move that placed him on the international circuit and set the stage for his rise as one of the featherweight division's most dangerous and creative competitors.

Featherweight Dominance Across Formats

Competing in the featherweight division — Peso Pena, 70kg/154lbs — Moizinho established himself as one of the IBJJF circuit's most consistent performers across both gi and no-gi formats throughout the 2010s. His most commanding run came in the no-gi discipline, where he claimed four consecutive IBJJF World No-Gi Championship titles from 2014 through 2017 — a sustained stretch of excellence that placed him among the elite of his generation at that weight class.

A Full Calendar of Titles

Beyond the No-Gi Worlds, Moizinho accumulated gold across the full breadth of the IBJJF calendar. He won the IBJJF Pro League Championship in 2014 and claimed Pan No-Gi Championship gold in 2012, 2013, and 2014. His dominance at the IBJJF American Nationals — collecting titles in both gi and no-gi formats between 2011 and 2015 — underlined his consistency at the continental level. He also reached the gi World Championship podium multiple times, earning 3rd place finishes in 2016 and 2018, and remained a Pan American Championship fixture across more than half a decade, finishing 2nd in 2015, 2016, and 2017, and 3rd in 2014, 2018, and 2019.

Transition to Coaching and Masters Competition

As his career matured, Moizinho added the IBJJF World Masters Championship to his résumé, winning at the Master 1 level in both 2016 and 2017. He competed out of Caio Terra's academy, CTBJJA, during his early years in the United States before moving in January 2015 to serve as head jiu-jitsu coach at the Gracie Fighter gym — a role that marked the beginning of his evolution from competitor into coach and institution-builder. Throughout his professional career, he has represented the United States on the international competition stage.

The Finish That Defined a Career

Among Moizinho's many competition highlights, one moment stands above the rest in sheer visual impact: a rolling Loop Choke that put Marcio André to sleep in the semi-final of the 2016 IBJJF Pan Jiu-Jitsu Championship. The finish — a spinning, seamlessly executed stranglehold — became one of the most circulated submission clips in the sport and remains emblematic of his innovative, technically adventurous approach to grappling. That semi-final run ended at the final, where Paulo Miyao defeated Moizinho 6×6 on points via advantages to claim the featherweight title; Moizinho placed 3rd at that event.

High-Profile Finishes and Submission Sharpness

Long before that moment crystallized his public profile, a quick footlock finish over UFC star Nate Diaz introduced him to audiences beyond the dedicated BJJ circuit, demonstrating his ability to perform against high-profile opponents from the broader combat sports world. The match served as an early signal of the submission sharpness that would define his career.

That finishing instinct showed no signs of fading as Moizinho moved into the masters divisions. At the 2022 IBJJF World Masters Championship, he claimed the Master 2 featherweight title by submitting all five of his opponents — a perfect sweep through an entire bracket without a single match going to the judges. The performance confirmed that the same predatory finishing game that had made him feared in his prime remained fully operational deep into his masters career.

Throughout the 2010s, Moizinho navigated a featherweight division stacked with elite talent, including Joao Miyao, Paulo Miyao, and Marcio André — competitors who tested him at the highest levels and shaped his competitive record.

Breadth Over Predictability

Osvaldo Moizinho has earned a reputation as a "master-planner" on the mats — a competitor whose defining quality is not explosive athleticism but methodical, systematic dismantling of opponents. Where some elite competitors stake their careers on a signature position or a single dominant weapon, Moizinho built his game on breadth, variety, and strategic unpredictability.

By the Numbers: A 2016 Competition Analysis

A 2016 competition study published in Jiu-Jitsu Style (Issue 30) examined his IBJJF featherweight matches from 2011 through 2015 and put numbers to what observers had sensed intuitively. The study found a 73% overall win rate, with approximately 72% of those wins ending in submission. More striking than the rate itself was the range: the authors identified seven distinct submission types across his finishes — a variety they described as the greatest they had encountered in a studied sample. The same philosophy extended to his passing game, which was predominantly standing-based (nearly 80% of passes) and spanned seven different pass styles. His sweep-to-pass ratio came in nearly even at 10:9, reflecting a balanced approach between guard work and top pressure that resisted easy categorization.

The Arsenal in Practice

Perhaps the most revealing detail from the study was that De La Riva Guard was the only technique Moizinho used more than twice in the observed sample. That finding did not indicate a De La Riva specialist — it indicated a competitor so broadly distributed across his full arsenal that no single tool crossed the threshold of repetition. The study also noted his effectiveness at neutralizing opponents' Berimbolo attempts and his willingness to counter with his own berimbolo from that same entanglement, while observing that he tended to avoid bottom Half Guard as a deliberate positional preference.

At the center of his submission identity sits the Loop Choke — particularly the rolling variation — alongside overhook-based attacks. These are the techniques most closely associated with his name, the ones he returns to in instructional contexts, and the finishes that define his most memorable competition moments.

Beyond his individual competition record, Moizinho's lasting contribution to Brazilian jiu-jitsu may be the institution he co-founded: Ares BJJ. He serves as head professor at Ares BJJ Goodyear in Arizona, operating as the academy's primary instructor from its inception and mentoring athletes across all stages of development.

The team's competitive trajectory under his leadership has been notable. In 2022, Ares BJJ claimed a team victory at the No-Gi Pan American Championship — a result that reflected both the depth of talent Moizinho has developed and the competitive culture he has cultivated within the organization. The team's growth from a newly founded academy into a championship-producing program mirrors the same systematic approach that characterized his competition career.

His continued presence on the mats as an active masters-level competitor gives his coaching a dimension that purely retired instructors cannot replicate. When Moizinho teaches a submission sequence or a strategic framework for breaking down opponents, his students receive instruction from someone simultaneously applying those same methods at elite competition level — a continuity between competition and coaching that defines the environment he has built at Ares BJJ Goodyear.

Moizinho's influence on Brazilian jiu-jitsu extends well beyond competition results and academy walls. Through seminars, online instructionals, and active social media engagement, he has built a global teaching presence that brings his technical innovations to practitioners who will never set foot in Goodyear, Arizona.

The rolling Loop Choke occupies a central place in that instructional identity. After the 2016 Pan American semi-final finish against Marcio André spread across the BJJ internet, demand for detailed breakdowns of the technique grew substantially. Moizinho has consistently delivered — sharing setups, entries, and troubleshooting through tutorials that have reached practitioners at every level worldwide. His instructional content on overhook attacks and loop choke variations draws directly from the areas of his game where his competition record lends the most credible authority.

Having previously served as head jiu-jitsu coach at the Gracie Fighter gym before channeling his full instructional focus into Ares BJJ, Moizinho represents a model of the modern BJJ career arc: an elite competitor who transitioned organically into institution-builder and community educator without stepping away from the mats. His dual identity — active masters champion and full-time academy head professor — gives his teaching an immediacy and practical relevance that continues to resonate with students and practitioners across the global jiu-jitsu community.
