Golfology Illustrated

Version 5

A Common-Sense Solution to Learning Golf, from PGA Life Member Dr. Greg P. Ortman.

This book explains, in a clear-cut fashion, the why-isms without golf's confusing how-isms.

Golf is hard. Really hard. Not because you’re doing it wrong—but because you’ve never been taught why the game works the way it does.
In Golfology Illustrated, PGA life member and nationally recognized instructor Dr. Greg P. Ortman brings 50+ years of playing, 40+ years of teaching, and over 20 years of academic research to the table to help you finally understand the “why” behind the “how.”

Whether you’re a beginner, weekend warrior, or seasoned player looking for a mental edge, this book offers the insight and clarity you’ve been missing.
