About Us

Welcome to Cortez Full Circle Martial Arts

"We welcome you to scroll through our website, FB and IG pages and if you feel this is a good fit for you, we welcome you to take the next steps and reach out to schedule a Free Trial Class. We opened our doors to our first academy in 2001 in Manteca, CA. At that time, we only taught Mitose’s Kosho-Ryu Kenpo. In 2008, we added the Brazilian Art of Jiu-Jitsu and relocated to a larger facility. We always look for ways to accommodate our students, so when they requested Muay Thai, we delivered by adding this program in 2018 at our much larger facility.   We have now also added Youth Wrestling and an MMA Class. We invite you to stop by and check out our 4500 sq ft facility in Lathrop and see what all the fuss is about! 

"See YOU on the Mat!“
