I have taken lessons from others but I feel that the training sessions that I had with Mark were by far better for improving my swing than the others. He is very knowledgeable as most pros are but maybe it is how he explained things that helped me learn and correct some bad swing habits. He also installed new shafts in my irons, they are perfect and my scores this year are proof that he knows his stuff and the days of not knowing what golf swing I might have when I show up at the course are over. The confidence I have in my swing has been restored. Thank you
