Peter "the Greek" Letsos
Peter “the Greek” Letsos is a highly respected Brazilian Jiu-Jitsu black belt under Carlson Gracie Jr. and the founder of Rio Jiu-Jitsu Academy in Chicago. A veteran of the sport’s “second wave” in the United States, Pete spent four transformative years living and training in Brazil, where he honed his skills alongside legends like Osvaldo Alves and at the Carlson Gracie headquarters. His nickname, “the Greek,” was affectionately coined by his Brazilian teammates who found his surname difficult to pronounce but his dedication impossible to ignore. A multi-time Pan American medalist and Gracie Invitational champion, Pete is internationally recognized as a master of the “lost art” of wristlocks, famously summarized by his slogan and instructional series, “Wristlock the World.” His teaching style is deeply rooted in the gritty, technical pressure of the Carlson Gracie lineage, making him a sought-after seminar leader for practitioners looking to bridge the gap between traditional fundamentals and creative submissions.
Rosa Walsh-McCann
Top Irish prospect Rosa Walsh has just been awarded her BJJ black belt by the reigning ADCC world champion Ffion Davies, becoming the first person to be promoted under Davies. Walsh has been a popular and prolific competitor all across the UK for quite some time, and has been branching out even further. She actually got one of her biggest tournament wins just a matter of days before Davies won ADCC 2022 in fact, as Walsh competed in the ADCC Open at the same event. Walsh now stands as the youngest female Irish BJJ black belt ever, at just 25-years old, as well as setting a record for being the first female black belt from Cork, and being the 6th female Irish-born BJJ black belt ever.
