About the coach
As a golf coach with extensive experience competing at every level of the game and thousands of hours of teaching experience, I have the ability to help students overcome any issue they may be facing on the course.
I believe that every golfer is unique and therefore, I don't teach a specific method, instead I focus on teaching the golfer. My approach is to ensure that everything from a chip shot to a driver shot should always relate back to helping the student achieve their desired impact conditions.
I am constantly seeking new and innovative ways to improve my coaching methods and the drills I use with my students are among the most advanced in the world, designed to accelerate the change as quickly as possible.
My areas of specialty include:
Long Game: I have a deep understanding of the the swing. I have a systematic approach that makes the decision making calculated and precise. I’m always working back to my 3 key areas:
- Strike
- Start line
- Curve
-
Your whole blueprint will be built around having a tight shot dispersion with predictable curve.
-
-
Short game: My goal is to give you a very high short game IQ which will help you access the lie, choose the correct shot and execute it under pressure. Learning shots is an excellent way to develop your short game.

Ruddy is the best I have worked with. Absolute pro and understands what is right in the golf swing. Laser focus and very consistent feedback daily on videos I send him on Skillest.

Been getting lessons off David for about 9 months, a mixture of in person and online. Made huge changes to my swing in a short period of time. Keeps everything simple with the same core principles behind every lesson. Would highly recommend to anyone looking to improve.

A Brilliant lesson on improving my wedge play with David. He really helped me understand the mechanics of the swing better and gave me helpful drills to practice and bring to the course. Id highly recommend David if you have areas of your game to work on.
