Konstantin quit American Gymnastics Institute in Chesterfield MI. It came down to realizing the coach/club owner Jeff allows demeaning behavior in the gym that it becomes an embarrassment to the sport itself. Hiring a "coach" who doesn't have ONE CLUE about how to really coach! Knowing that this so-called boys coach sits on his phone during training, asking the boys if they have taken their pills for retardation, the older boys gymnast vaping in the bathrooms, and tearing down the self-esteem rather than building it up. They use humiliating and disrespectful behaviors as a "teaching" tools. The boys barely showed any skill progression throughout the past 2 years. When I called to complain to the club owner, Jeff himself called the coach a M..... F......PRICK, NO GOOD, USELESS and now once again he can't find a coach knowing he is going to lose the boys team. But he didn't have the decency to communicate to the parents. Am I suppose to feel sorry for him? He had known this for quite some time and instead of taking some kind of action to stop what was going on, he decided to keep quiet till the season ends, leaving the boys in limbo looking for new places to do gymnastics. Bottom line Jeff is a horrible owner, there is a reason why even the bad coaches at AGI quite, Jeff only cares about making his money. That's the real reason why he didn't tell the parents that another coach quit at AGI. The only reason all this came out is because Konstantin told his teammates a month ago. Stay away from AGI, find another gym. Don't send your children to AGI for classes or for a competitive team. The only reason this place gets one star from me is that yelp doesn't allow 0. We switched to a real gymnastic institute where they hire professional coaches and are very happy we did. Looking forward to a new successful gymnastic year!
