I recently visited Big John McCarthy's mixed martial arts school in Valencia and was blown away by how amazing it was. It's HUGE and has everything you could ever need...it even has an octagon just as big as the UFC's and they have tons of UFC memorabilia! Big John was there when I visited and he was super cool!! I did a free day pass and the instructors were really knowledgable and nice. I just wish I lived in Valencia!! I will definitely go back when I am in the area again!! A++++ facility and staff!!!
