Club K wants only the best for those girls. Maybe the management saw something that you didn't. As a former parent of a Club K student, we paid them tons of money to make the very best players possible. As parents, we trust their knowledge and experience. I suggest you stop worrying about something you can't change. As instructors, they do not have time to listen to rumors, message boards, or consult parents about instructor changes. Rest assured if you continue to trust them and let them do their job it will all work out for the best and you will be glad of it.
