John Kuentzel is a Registered Piano Technician with the Piano Technicians Guild. He graduated with a Bachelor of Arts degree from Catawba College in 1974. From the fall of 1975 through the spring of 1976, he was enrolled at the Sims School of Piano Technology, where he learned to tune by ear and to perform the most common piano repairs. From 1976 to 1977, he worked in a piano rebuilding shop where he learned to rebuild piano actions. Since that time, John has worked for various dealers, as well as on his own. In the course of his career, he has gained experience stringing new pianos and restringing pianos being rebuilt. As well as tuning in homes, John tunes for schools, churches, recording sessions, and the concert stage.
