About Us

Rock City MMA is all about the teaching of Martial Arts, Mixed Martial Arts and the belief that it is for anybody and everybody! A great way to get in shape, stay in shape and develop athletic skills superior to most. We believe that when you feel beat down in the cage of life, or you feel the grinding pressure of ground n pound at work or at school, the skills you have acquired through MMA training will bring you victory.

Knowing that Jesus, your ultimate Cornerman, is there to bring you water in between rounds, gives us hope and courage to fight another round. We want to fight the good fight of faith. Knowing that with God beside me, we can accomplish anything we set our mind to.

The life skills that are taught to the students will help develop Leadership, Courage, Respect, Discipline, Focus, Confidence, Integrity, and Humility.
