I took three classes with Linda V. Taylor at the NQA Show in Columbus a few years ago. The best investment I made concerning my mid-arm. She was wonderful, down to earth and very, very humble. Made me feel SO comfortable. I was a total newbie, and by the time I left I wasn't afraid to use my machine at all. I was chompin' at the bit to get home and try it out - and I have a Hinterberg Voyager, not a Gammill. If I had the money, I'd take more classes from her. She was, hands down, the best teacher I ever had!
