In 2009 Andrew Getson joined the Grayhawk Learning Center staff. He brings with him a decade of experience gained on the Asian, Australasian and Nationwide Tours. During that time he carded a handful of top 10 finishes including 1st place in the Sedona Open, 2nd place in the Thailand Masters and 2nd place in the South Australian PGA Championship.

Getson’s successful golf instruction career is highlighted by a few of his high-profile clients including President Bill Clinton and Prince Andrew. But his ability to effectively communicate the fundamentals of the game of golf is equally helpful for his non-head-of-state/royalty clientele.

Getson began his life in golf in much the same way as a few other notable Australian golfers such as Stuart Appelby, Robert Allenby, Aaron Baddeley and Geoff Ogilvy, at the prestigious Victoria Institute of Sports. From there he went on to play for one of the highest regarded teams in the country – Victorian State Golf Team – where he earned a few state titles.

I want you to hit it better, and I want you to think and feel better too. I’m blessed to have a passion for people and for encouraging them to get more enjoyment out of their golfing experience.
