    The only reason I stayed here was because of the pricing. I only took Jiu Jitsu there, but my experiences were not all that pleasant. I had my ankle broken due to an overzealous heel hook, I’ve had multiple joints and muscles tweaked countless times, and the final straw was having the instructor himself injure my wrist, which after two months, still hasn’t properly healed. In short, this gym should be somebodies last resort, and then, only if your desperate.
