Ruthann Pike
Ruthann opened the original repair counter in 2009 after eleven years assembling and repairing clubs for two Arkansas pro shops. She is the one who started keeping measured specifications in a filing box, which is where the whole ledger idea came from, and she still runs the majority of full bag sessions herself.
Her particular interest is the top of the bag, where she argues most golfers carry two clubs doing one job. If you book a driver or fairway session on a weekday morning, you are almost certainly working with Ruthann.
