What is TPI?

TPI (Titleist Performance Institute) is the world's leading educational organization dedicated to the study of how the human body functions in relation to the golf swing. For over twenty years, TPI has gathered the world’s largest technical database of the game’s top Tour professionals as well as every-day golfers. TPI collects 3D motion capture, force, pressure, launch monitor, strength, power, and movement data on every player that visits the TPI campus. Using this data, TPI discovered how a properly functioning body allows a player to swing a golf club in the most efficient way possible. Conversely, TPI determined how physical limitations in a player’s body can adversely affect the golf swing and potentially lead to injury. This relationship is what TPI calls The Body-Swing Connection and is the foundation of all professional Certification courses offered by TPI.

TPI’s Mission

TPI’s mission is to educate golfers and industry professionals on the Body-Swing Connection through its one of a kind TPI Certified educational program.

TPI’s Philosophy

TPI believes that golfers should match their swing style to their movement capabilities. The philosophy is simple:

There are an infinite number of ways to swing a golf club. However, there is one most-efficient way for each player to swing a club and it is based on what they can physically do.

TPI’s Assessment Screen

If you don’t assess, it’s just a guess.

To achieve an efficient swing, a golfer must first be screened. A proper screen involves an assessment of swing mechanics, biomechanics, physical fitness, movement quality, current health, and injury history.

Founding Membership Opportunity

A limited number of athletes will be accepted into our Founding Member Program—an opportunity to train within a structured, data-driven golf performance system designed to improve distance, consistency, and long-term durability.

Most golfers never address the physical limitations that directly affect their swing. This program is built to improve the way your body moves, connect those improvements to your swing, and develop more efficient, repeatable performance over time.

Take advantage of this unique opportunity to train your body, optimize your swing, and elevate your game. Registration links and program details are provided above to secure your spot today.
