I am not sure if this golf swing instruction company is available in Europe, but I use them every so often when traveling around the USA. Build a game you can trust from tee to green with GolfTEC, America's #1 Golf Lesson They are associated with Golfsmith, but also have a few independent stores around the country.

The part I like about their process is being able to pull up a swing, or putting stroke training session after the fact on my computer and review what the instructor and I found, and discussed. This to me is a good off season training scenario, since you can revisit your instruction anytime you want, no matter how far you are from the instructor.

They are a bit pricey, but good at what they do. Then again unless you are a golf phenom with natural abilities, at some point you are going have to get quality, personal instruction to be able to play golf with the top 5% golfers in the world on an every day basis. GJS
