One Nation Jiu Jitsu

One Nation Jiu Jitsu in Smyrna, Tennessee, was founded by Professor Cliff Fonseca, a third-degree black belt with over two decades of experience under Luiz Palhares. Since opening its doors in 2010, the academy has become a home for students of all ages looking to train Brazilian Jiu-Jitsu with a modern, practical approach. Professor Cliff leads a team of instructors that includes black belts Jeovany Ortiz, Tyler Jackson, Doug Newburn, and Clay Oldham, each bringing their own background and teaching style to the mats. The coaching staff’s focus is on day-to-day development, ensuring every student—whether young beginner or adult competitor—has the support and training they need. The academy is especially known for its structured youth programs and after-school offerings. Kids can start training in the ASP Blue or Red Block classes, which are designed to build skills and discipline from an early age. The after-school program provides transportation and a safe place for children to learn and grow, with Professor Tyler Jackson managing these programs and bringing his education background into the mix. For families in the area, this program offers both convenience and a meaningful developmental experience rooted in martial arts values. Adults at One Nation Jiu Jitsu can train in both gi and no-gi formats, with a particular emphasis on no-gi as a core part of the academy’s identity. The schedule includes early-morning classes, open mat sessions, and specialized instruction, such as the Women’s Only class led by brown belt Sadie Beard every Sunday. The curriculum balances technical fundamentals with live sparring, and instructors like Doug Newburn integrate strength and conditioning principles into their teaching. Drop-ins are welcome, and the facility is wheelchair accessible, making it easy for newcomers to experience the academy firsthand.
