At D-BAT Tulsa, lessons are taught with the ballplayer as the focus while involving the parents during the lesson.  We have great instructors who can instruct players at every level for improvement. However, our instructors can not be at the ballplayer's games, so they rely on the parents for feedback on how the player is doing in game situations.
