Golf, for me, is more than a sport - it's my zen. With over 17 years of experience both playing and teaching the game, I have developed a unique, holistic approach to golf instruction. My golfing journey extends beyond personal play, and into the world of coaching. My goal as a coach is to equip you with not just technical skills but a comprehensive understanding of the game that elevates your performance to the next level. Whether you're a beginner needing basic tips or an experienced golfer seeking refinement, I'm here to guide you through your golfing journey. Let's begin!

"Easily explaining the basics that made a difference in the beginning swing to the end swing of that lesson.

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.

For the past five years, I've dedicated myself to teaching golf, focusing primarily on juniors aged 5-17 while also offering lessons to adults of all skill levels.

My background in high school and college golf not only fuels my passion for the sport but also enriches my coaching with firsthand competitive insights.

"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.
