Bobby Smith


From an early age, Bobby is what you would describe as a martial arts enthusiast. Growing up in Atlanta in the mid 80’s he was a fan of many martial arts TV shows and movies. Some of his early heroes were the likes of Bruce Lee, Sean-Claude Van Damme, and Steven Seagal. So it was no surprise that at the age of 8 he began training in Kenpo Karate.

As he came of age he maintained his passion for the combat arts by also training briefly in Taekwondo, Kick Boxing, Hapkido, and even a hybrid martial named Tae Kwon Jitsu. Until one day hoping to add a more extensive grappling pedigree to his repertoire he found Gracie Jujitsu. Now holding the rank of blue belt he hopes to give back to the art that has given him so much.

Bobby is a devoted father, business owner, and ambassador for the life-changing art of Gracie Jujitsu.
