My kids are in a tennis program where they love the other kids, but can't stand the coach. Should I move then to another program and a better coach?

@uncalled4 He only talks with the kids when the parents are there or as soon as they pull up to the courts. The kids see that he is a 2 faced when he does this. He is also a big gossip and drama queen and talks about other parents and kids (in a bad way) in front of the kids and parents. He has been very divisive with families and tries to make people look bad if they leave him or have a problem with him.
