The Titleist Performance Institute (TPI) is the world’s leading educational organization and research facility dedicated to the study of how the human body functions in relation to the golf swing. Since its inception in 2003, TPI has studied thousands of golfers ranging from the top professional tour players to weekend enthusiasts. TPI discovered how a properly functioning body allows a player to swing a golf club in the most efficient way possible. Additionally, TPI has analyzed how physical limitations in a player’s body can adversely affect the golf swing and potentially lead to injury. With the assistance of a TPI certified clinician you can finally discover the true potential of your golf game. Andreas will identify your specific physical limitation that may stand in the way of your ability to play to your full potential.
