Not a good experience. Very pricey, promised 30 min practice sessions with my package and even on course lesson when spring rolled around, but they never follow through. I too went to Tim mercer, nice guy, but hes not a teacher. Golf tech as a whole teaches the ever dead stack and tilt principal. Weight forward 60% or more, take backswing waaay inside around body, finish with locked elbows in front. Weak swing, you will never get power or consistency from this technique. They say you will bottom club out consistently, but they forgot to tell you that maybe you will if you play 250 rounds a year and you never ever want to hit a fade or straight ball. Just ask Aaron Baddely and Sean Foley who almost ruined Tiger. If you have any kind of back issues, stack and tilt will destroy you. I can see why other reviewer said Tim ruined swing. It will cause you to have OTT move coming that far inside on takeaway. I told Tim at onset I wanted nothing to do with S&T. He was useless and lost from that point on. Sad thing is he would argue with me at lessons and talk down to me if i wasnt getting what he was teaching. I went from a 13.3 index to a 23 index in 3 months with them. Was miserable and shot the worst scores in decades trying to learn what he taught, he really didnt care. I stopped going, went to a club pro when weather broke and 3 months of unlearning bad golf tec habits and hard work later I was down to a 11.1. I never even went back to Golf Tec for my remaining lessons I paid in advance for. Sad thing is they never called to say I had more remaining or to see why I never came back. This was second time this happened. Oak brook was same. I still have paid in advance for lessons there from 3 years ago. This is a waste of money folks, they are all the same. Go to a local course club pro. Golf tec is a franchise joke and only know one swing technique. There way or the highway, Doesnt matter age, body type, or personal issues. Stack and Tilt or a remnant thereof is all Golf tec is. Stay far far away if you truly want to get better. read more
