Private Golf Lessons & Coaches in View Park Windsor Hills, CA

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!

"That lesson sparked a fresh grip change and clear goals, plus I can feel the swing staying steadier. A few head-still, weight-shift drills will really lock it in, and I’m excited to continue.

Over 35 years immersed in the world of golf, I offer expertise from modern tech to the mental aspects of golf to help you compete and develop your best game. I’ve caddied on the LPGA tour and competed at the professional level. My passion lies in helping students of all levels unlock their full potential specializing in long game, short game and positive mindset techniques. I'm dedicated to a balanced custom approach that cultivates both skill and a genuine love for golf.

"I was only fortunate enough to know and work with David Byrne for a little over a month before he relocated to California, but that short time made a lasting impact on my game. I truly enjoyed his passion for golf and his genuine desire to help players get better. David often went out of his way to coach me between lessons whenever he wasn’t already busy teaching others—something I greatly appreciated. At 67 years old, I’m not looking to completely rebuild my golf swing, and David understood that from day one. His approach focuses on helping you find a swing thought that works for your swing, rather than forcing a onesizefitsall method. He helped me understand my swing plane and path, and how to consistently get into the right position before impact. After that, his favorite encouragement was always: ‘Turn the corner!’ And it worked. David is a talented instructor, an insightful coach, and an allaround good person. And watch out for his son—just a wee lad with a fabulous golf swing already! David’s passion clearly runs in the family.

Playing for the past 10+ years and have extensive teaching experience with athletes, kids, and people of all experience levels. 7 handicap. Ready to help with the driver, woods, irons, wedges, short game, putter, or all around game. Have worked with pure beginners all the way up to scratch players.
