I chose to take up the guitar later in life (after retirement). I did not read music nor did I feel that I had any rhythm. William was extremely patient with me and brought me to levels that far exceeded my expectations. William has a rare ability to be able to put a person at ease and reduce their tension level. Sometimes it was through talking and sometimes through playing. He was able to read my apprehension level very well and seemed to always choose the correct method. I moved away from the area and thus far have not found a guitar teacher with the same abilities. Regardless of age or ability, I would recommend William to anyone. Were it not so expensive I would gladly fly back to Phoenix once a week to continue my lessons with William.
