Coach Jo-el bio coming soon

Mohammad Ibrahim

Coach Mohammad started martial arts when he was at the ripe age of 12. He first got his black belt in Karate under Master Koo in Cartersville.  He then progressed onto MMA and BJJ once he was 15. At 16 he was entering grappling tournaments and consistently winning gold in the teens division. His time has now only been completely focused on BJJ, usually training 2-3 times a day and 6 days a week.  6 years into BJJ now Mohammad is a purple belt who has competed against and submitted multiple Brown belts in his career. Although he loves to compete,  passing on his knowledge and experience to others is an absolute joy for him. His biggest goal in his BJJ career is to become a highly decorated world class black belt and also make a positive impact in his student’s lives.
