I'm Katy, and over the past four summer school seasons, I've taught junior golf group lessons in camp clinics, catering to ages 3-18. Beyond that, I've developed my coaching skills through 1-on-1 instruction, working with individuals ranging from 14 to 55 years old. Back in 2017, I had the privilege of volunteering as a health & wellness advisor for a D1 Women’s Golf Team for a semester. On the competitive front, I've played against some top golfers like LPGA Rookie of the Year Jillian Hollis, Jessica Porvasnik, Clare Legaspi, Cindy Oh, and more. Before diving into our first lesson, I always start with an assessment to understand each player's personality, their mental game approach, and the unique ways in which they learn. From that foundation, our inaugural lesson will focus on observation—watching how you swing or play. After which, we circle back to mastering the fundamentals, complete with personalized drills. You get to decide the lesson's focus, be it putting, chipping, short game, or even a 9-hole playing lesson, all based on your golf aspirations. I believe in nurturing from within first. The ideal player I work with understands that a positive mindset is the foundation for a successful physical game in golf.

"Gave the lesson as a gift to my by bestie. Katy was very communicative regarding the lesson and inquired about what goals we had for a lesson outcome. She arrived on time and prepared. My friend really enjoyed the lesson and constructive feedback. He said was very cool and easy to learn from. She even would crack a joke from time to time to make the lesson more stress free. A total success for a 1st lesson. I recommend her as an instructor for anyone wanting to get better at golf no matter what level you are.

"I’ve been taking lessons with Coach Chae for a few months now, and the progress I’ve made is incredible. Before working with him, my golf game felt frustrating—I struggled with consistency and often felt unsure about my swing mechanics. Coach Chae helped me break down my swing into manageable parts and focused on building solid fundamentals. What I appreciate most is his patient coaching style. He takes the time to watch my swing carefully and gives detailed feedback without rushing. His drills are practical and directly translate to better performance on the course. Since starting with Coach Chae, my ball striking has improved significantly, and I’ve lowered my scores by several strokes. My putting and short game have also seen great improvement thanks to his targeted practice routines. I now approach each round with more confidence and a clearer understanding of how to play smart golf. Coach Chae is definitely the coach you want if you’re serious about improving and enjoying the game more.

"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.
