I was fit by Jim two years ago and was pretty amazed by how much better my ball striking became. I'm a 9 HCP.
My wife is 5'2" and a 30-something handicap. I wanted her to have the advantages of custom fit clubs. She was very apprehensive about getting fit. But after spending her first session (woods/hybrids) with Jim she was very excited about her new clubs and found the whole experience interesting and enjoyable. Her second session for irons was just as satisfying.
Jim is a real pro, and is great with the personal side of things as well as the technical end.
