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. 

Old School Fundamentals and New School Technology
Golf is counterintuitive—sometimes you have to try hard to not try hard.
We’re looking for effortless power, not powerless effort.
There is no one swing for everybody—but everybody needs one swing!
