I took 3 lessons with Duse Dronen working out of Jefferson Park Golf and my game has improved immensely. He watched me swing and video taped it. He then explained to me by watching the video that I was not opening my club face on the back swing and was coming over the top which I did not think I did. The video showed all my mistakes. He showed me the proper swing and had me work on that. My slice has pretty much disappeared! How exciting is that? On my last lesson he took me to the short course and had me work on my pitching and putting which was definitely needed. I will work on the things he has taught me in my swing over the winter and maybe I will see him again for a tuneup come spring. He was very reasonably priced and I would highly recommend him for anyone that has a slice or hook or want to improve on their swing. Thanks Duse! You are making golf fun.
