Keith at Allegro Piano Works rebuilt my mom's Ivers & Pond upright about three years ago and did a great job. He has also worked on the Mason & Hamlin 'Parlor Grand. He tunes both at least once a year. I would recommend him without reservation.

I stumbled upon Keith Comparetto twenty-one years ago when an elderly relative gave my family her upright piano. She had bought it herself in the early 1900s, and we wanted to honor this gift and do it justice -- without breaking the bank. Keith gave us a realistic idea of the instrument's quality and repairability, along with a repair plan at various levels of restoration. We found his quotes completely reasonable and decided on a mid-level approach.

The result was fantastic, and this piano became the musical center of the house. Our kids were four and five years old at the time, and thanks to Keith's work, they grew up with this constant source of beauty at their fingertips. Each wound up majoring in music. Eventually, Keith restored another 100-plus-year-old upright for me at a different home, and all the while he's kept both pianos in tune, making whatever small repairs might be needed along the way. I can't imagine going to anyone else.

Keith has cared for our family heirloom Steinway for several years now. It was not always cared for so well, but Keith finessed repairs and tweaks to keep it playing and looking beautiful. What's more, he is super polite and respectful when working in our home; he was especially kind to my elderly mother who used to hang around and watch him work! Always cheerful and helpful. And he was even able to produce an expert appraisal for our insurance company. I highly recommend his services.
