Welcome to Golf Lessons by coach Kollar, where passion meets precision. Mile Square Golf Club in Fountain Valley is my home course, where I’ll often be found, sharpening & working on my game. As a trained golf instructor, I specialize in offering a personalized swing and short game lesson in golf. Whether you're a beginner, eager to learn the basics and fundamentals of the game, or intermediate player aiming to refine your overall golfing ability, the lessons I implement are designed to enhance your overall golf game, while most importantly helping you to enjoy the time you spend practicing. As a graduate of Golf Academy of America, Carlsbad, California (unfortunately no longer in business), I studied the golf swing, psychology of golf, and complex teaching methods as well as golf game management. I also learned how to build and assemble golf clubs, as well as expanding my knowledge on the vast and complex rules of golf. During my 2 years at GAA, beyond my studies, I competed at a collegiate level, making the competitive Golf Team each semester I attended. I came to understand that there are no two identical golf swings. My job is to influence you to find the mechanically correct way to improve your swing and develop your short game, to help you enjoy golf more than you ever have!
