Checkmat Corona BJJ was founded in 2014 by head instructor Jimmy Tat, a black belt champion and respected coach with experience at the highest levels, including the UFC. The academy is part of the Checkmat lineage, known internationally for its technical depth and competition pedigree. Alongside Jimmy, the teaching staff includes co-founder Cindy Almonte and a team of skilled instructors such as Danny Bautista, Jacob Klein, Tacae Harvey, Ricardo Gonzalez, Hieu To (kids instructor), Tony Lopez, Daniel Zepeda (assistant kids coach), Rae Lohr, and Lui Hung, each bringing their own experience to the mats. Training at Checkmat Corona centers on Brazilian Jiu-Jitsu for both adults and kids, with an emphasis on technical progression, live drilling, and sparring. The academy’s curriculum supports students interested in sport BJJ—both gi and no-gi—as well as those preparing for mixed martial arts, reflecting the breadth of experience among the coaching staff. The presence of multiple instructors allows for focused instruction in different age groups and skill levels, including dedicated kids’ classes. Open mat sessions are a staple here, offering students from all backgrounds the chance to roll, experiment, and refine their game in a less structured environment. The facility is wheelchair accessible, and visitors are welcome to drop in, making it an inviting space for both locals and travelers seeking quality training in Corona, California.
