Private Golf Lessons & Coaches in Los Alamitos, CA

Golf humbled me for years before it rewarded me. I spent over two decades playing and competing at the Mini-Tour level, grinding through the same frustrations that every serious golfer knows — working hard, doing everything you think is right, and still not getting the results you’re after. What eventually changed things wasn’t talent. It was finally understanding why the swing works the way it does. The mechanics, the cause and effect, the things that nobody explained clearly until I dug deep enough to figure them out myself. That took years. A lot of them. That’s exactly why I started coaching. I didn’t want my students to spend years piecing it together on their own. Everything I learned the hard way — I put it straight into the lesson. Over 2,000 lessons in, my approach is built on one thing: giving you a clear, honest picture of your game. I use high-speed camera technology so you can see your own swing on screen and understand exactly what’s happening — no vague feelings, no guesswork. Just real information you can actually work with. I coach in English, Mandarin, and Burmese, and I take pride in making sure every student — regardless of background — walks away with full clarity and real confidence in their next step.

"Best coach i’ve ever worked with, super patient and a lot of attention to detail. Came prepared with his tools and started from the base of exploring my swing and then fixing it.

"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.

I’ve been playing golf since I was 1 years old. Yes 1 years old. I played golf at the highest level. I had success in junior golf, amateur golf, college golf, and professional golf. Now in a different stage in my life, I am coaching and giving lessons.
