Calvin is a true professional, I have a cable Nelson that is very old and has been out of tune for as long as I can remember, he walked me through exactly what needed to be done and really worked with me, I knew this piano was not going to be an easy task to get sounding good again and he worked absolute magic on it.

We highly recommend Calvin. He did a fantastic job tuning my piano and was quick, efficient, and responsive. I reached out to him and he was able to come the very next day, which I really appreciated. He was professional, knowledgeable, and my piano sounds great now. We would definitely use him again.
