Please be aware of a man by the name of Horatio Martinez aka Marty who was transferred to Hot Ground Gym in Vernon Hills. While he was at the Arlington Heights location he physically abused my son. This was all caught on video, as you can see in the police report, however the owners of the gym have decided to keep him employeed and working with young children. In fact they made him the operations manager when the transferred him. My son attended Boot Camp with him for months and all seemed well but on day two of camp when he was unsupervised and no parents were around this is when he decided to abuse my son. Please be aware of this man and the choices this business have made and keep your hundred safe!
