I have been a life long high handicap golfer, and after recently retiring I decided to commit to finally fixing my golf swing before it was too late. For many decades, and as a result of trying to teach myself the proper fundamentals of a sound golf swing, I had developed many very bad swing habits, and I knew that wherever I went and whomever I decided to work with, they would have to help me "un-learn" those bad habits and build a new golf swings pretty much from the ground up. A good friend of mine, and a very good golfer in his own right recommended GolfTec. He hadn't actually taken lessons there himself, but friends of his had (in Florida) and raved about it. I signed up for a 10 lesson package after the initial swing analysis. I am now 8 lessons into this program, and the results have been extremely impressive. My handicap has only dropped a few strokes thus far, but these guys literally are rebuilding my swing from the ground up - and due to the issues listed above, that's what I wanted to do. The lessons and instruction from the professional instructors at GolfTec Halsted Row are first rate. My instructor, Ben Thulin, really understands the golf swing, and the way he explains it works very well for me - lots of explanations relate to physics - (but simple, basic physics), which I can readily absorb. And, all of the instructors at this facility (Don, Brian, Max, Jack, TJ) are incredibly friendly, and they're readily willing to help you any time you have a question or need some assistance or advice between sessions. Additionally, the facilities at the Halsted Row location are incredible. Each teaching bay is equipped with a tremendous array of technology that really helps the student understand what they're doing - during lessons, but also - and maybe most importantly - while practicing! After my first lesson, I asked my instructor where the nearest driving range was located so that I could practice. My instructor told me where it was, and then said "but I don't want you going there". He went on to explain that if I went to a driving range, I would practice and since I wouldn't be able to see my swing (as I can with the technology at GolfTec) I would most likely think that I was doing things correctly, but that I would probably not be (particularly in the beginning), and that I should come to the GolfTec facility and practice so that I could see what was happening on every shot - AND, when you're in a program, there is no extra charge for the practice sessions. An additional advantage is that when you are there practicing, the instructors periodically look in on you, to make sure you're working on the appropriate things, doing them correctly, and getting the most out of your practice sessions. I've worked with and taken lessons from (a limited number of sessions in each case) four of five golf pros over the years, and I've enjoyed them all. But, the instructors at this GolfTec facility in combination with the facilities and equipment/technology, are the best I've ever experienced. I've never made this much progress with really fixing my swing ever before with any other instructor/facility combination, in spite of spending an incredible amount of time "grinding" on the practice tee. On a final note, I visited one other GolfTec location in Florida a few months ago to get some practice in while I was down there (I spend a fair amount of time up North in Chicago, which is how I came to choose the Halsted Row location for my lessons this past summer). The equipment and technology at that location (Florida) were very limited (three practice/lesson bays) and were no where near as impressive as those at Halsted Row in terms of the technology/equipment. I highly recommend this GolfTec location and these golf professionals for anyone who is serious about improving their game, regardless of your current skill level. read more
