He’s learned under several world class BJJ practitioners including Sean Roberts, Jackson Nagai, and Ruben Charles Cobrinha. Being an immigrant, Coach Renzi believes that one should offer their service to the United States before earning the rights, opportunities, and privileges of living in and being an American. As a result, he enlisted in the United States Navy as a Hospital Corpsman. Coach Renzi has experience teaching both kids and adults and has competed internationally. Coach Renzi’s passion for learning and teaching will be a great tool in helping and supporting the growth and excellence of Unum Jiu Jitsu.
