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.

"In one session, Coach Katy noticed and fixed my problem. From my baseball grip, addressing the ball, to finishing my swing. Now my grip is relaxed, I bow and slightly bend my knees, and finish by hugging the tree. Coach Katy made me comfortable and made funny analogies to fix my problem. Great coaching

"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.

With a quarter-century on the green, I've cultivated a keen eye for unlocking potential in golfers of all levels. My approach blends classic techniques with personalized strategies for lasting improvement and on-course enjoyment. I'm passionate about helping you achieve your golfing goals.
