Five-time world champion Francisco "Sinistro" Iturralde founded Gentle Arts Jiu Jitsu in 2020 on North El Camino Real in Encinitas's New Encinitas corridor. The academy teaches Brazilian Jiu-Jitsu fundamentals through advanced competition technique for kids and adults, with grappling-specific conditioning protocols that align with sports-rehabilitation programming at Encinitas Physical Therapy nearby on Encinitas Boulevard. As an affiliate of the Gracie Allegiance network under Clark Gracie's San Diego headquarters, the school maintains a direct technical lineage to the Gracie family's foundational self-defense methodology. Complementary deep-stretch yoga and meditation sessions supplement the grappling schedule, integrating joint-mobility and recovery work into the weekly training cycle. Spinal alignment and musculoskeletal maintenance for high-volume mat athletes connect the academy to soft-tissue practitioners along the El Camino Real corridor, including Catalyst Health. Curriculum progression moves from positional escapes and guard retention in the fundamentals tier through submission chains, wrestling takedowns, and competition-pace rolling in the advanced track, with gi and no-gi rulesets trained in parallel.
