I started playing golf as a kid and have had many hours of lessons. I therefore think I can judge when a teacher has good knowledge of swing mechanics. After a 15 year layoff, I recently took up the game again and I found Mark for lessons. Mark nailed my problems within 5 minutes and made the corrections I needed. His teaching style is friendly and engaging, behind which is a great eye for analysis and improvement. I left with a clear understanding of what I needed to work on. I was very impressed with his teaching and the video was also very helpful. I’ll be going back for more lessons with him at Coronado Golf Course.
