The round that started it all.

GreenSense began with a personal observation — watching someone close face a challenge that quietly pulled him away from a game he had loved his whole life.

As Dr. Walker grew older, two knee replacements and a stroke made reading greens increasingly difficult. What had always been one of his favorite parts of the game slowly became one of its greatest frustrations — not from any loss of passion or knowledge, but from a physical barrier no amount of dedication could overcome.

That experience raised a question: what would it take to give golfers like Dr. Walker their confidence back on the green? The answer became GreenSense.
