At JPK Golf Instruction my goal is to help you create your golf game. I say "game" for a reason. Playing golf successfully involves a multitude of components--solid swing fundamentals, the right attitude, a good mental approach, and a confident short game to name a few. We evaluate your game and begin to turn your current weakness into your newest strength.
