Simon is a top-notch, consummately professional guy. He arrived as scheduled, fielded my many questions (I'm a musician, but not a pianist; the tuning was a Christmas gift for my wife), and really did a stellar job fine-tuning our piano. I appreciate that Simon verbally guaranteed his work, which made me feel more at ease. It's very apparent this craftsman is excellent at what he does, and the proof is pretty easy to hear: our upright now sounds concert-worthy. I see no point in ever looking for another piano tuner... As long as Simon's in the business, he has a customer in me.
