Mr. Bui replied promptly and clearly to my request, gave me a quick and convenient appointment, and showed up right on time, ready to work. Another tuner had been very negative about my 102 year old Kohler Campbell, but he was just the opposite. The first thing he did was sit down and play some really loud classical music! He told me (and showed me) that the piano still had its wonderful grand piano tone. He checked the strings and said they were strong, firm, and tight. He tuned the piano twice, since it had been so long, and to save the strings from extra stress, fixed the one sticky key, and then pointed out what he could do to further improve the piano for what I considered a very modest additional fee. He showed me in detail what was needed, and why. I went ahead with everything, and in the end, I had my wonderful piano back -- a piano I have played and loved since I was six years old (75 years). My children will be so glad to gather around it at Christmas.
