As am member, I have experienced the worst costumer service by Derek Marbles.This man has been extremely rude not only to me, but other members of the gym.
He clearly seems to be on a power trip given the fact that he was a big time college ball player and is now the GM at a crappy gym. I actually feel sorry for this man.
In addition to all of this, I have seen him having people he trains use the most dangerous forms and weights that are too heavy while they work out.DO NOT USE THIS GUY!!!
