When looking for a PGA Pro, before you book your first lesson you need to have a chat to see if your needs will match the Pros teaching style.
I find that the first thing I want to know from a prospective student is what are thet trying to accomplish. Do they need a "quick fix" to get them through an upcoming weekend tournament? Are they looking to re-build the swing completely? Or do they just need help with a small part of the game; putting, chipping, alignment, etc.
The place to find out you and your Pro are not on the same page is not on the lesson tee, it is in the shop before the lesson is booked.
