Driving range personal trainers
TheSandTrap.com Top Picks
Any exercise program should start with someone who applies objective baseline tests. This can be as simple as toe-touch, shoulder turn, etc. Without that baseline testing, how do you know if his/her program is helping you?
Someone with FMS or TPI certification is a good place to start. Of course not all of them are great but you're increasing your chances that a) the trainer isn't a hack, b) the trainer cares enough to take time off for professional development, and c) the trainer will use some objective criteria to evaluate. Less chance of wasting your time, money, and effort.
Going to either website will allow you to search for qualified people in your area.
Like any other business, there are great, good, mediocre, and terrible trainers. Don't forget you're the customer and have a right to interview a few to see who will work well with your needs.
Edit: feel welcome to get back to me about your needs and experiences and I can try to help more - decades of work in the business ought to be put to good use to help you out.
