Jonathan Grossman

Co-Owner, Brazilian Jiu-Jitsu Purple Belt, Head Jiu-jitsu coach

Jonathan began training in Brazilian jiu-jitsu at the age of 32, eight years ago, after years of interest in BJJ. He was 280 pounds with no athletic background and no idea how his first class would go, he always thought, things like BJJ were for “those type of people” and not for him. After mustering up the confidence to attend his first class he realized he had found the thing he should have been doing for years. He started to notice that the lessons he’d learn in jiu-jitsu applied to other aspects of his life…..hard work, goal setting, focus, mindset, all things that helped his success in jiu-jitsu also helped with success at work and in day to day life. After a short bit of time training he began to realize that he enjoyed helping others learn and decided teaching would be the main focus of his jiu-jitsu future.

Jonathan has traveled all over the country training and competing, and looks forward to continuing training, teaching, and growing with his Rogue Academy family!

An Air Force and war in Afghanistan vet, he is also currently an IT contractor.
