Piano Tuning and Piano Repair

Serving Los Angeles, Orange and San Bernadino Counties

If you have a piano in your home, consider yourself to be very fortunate. Whether you are young or old the benefits of piano playing (increased hand-eye coodination, spatial skill development, stress relief, mental health, enjoyment) have been well documented. For some, a piano might be one of the largest investments they ever make. For others, the piano might be a gift from a friend or relative. In either case regular piano tuning and occaisonal piano repair are necessary to keep your valuable instrument in good condition.

My name is John Caterino and I am a piano tuner and piano repair technician. I hope you will take some time to explore this site. Throughout the site I have attempted to answer some of the piano tuning and piano repair questions I have been asked. If you would like to talk with me, please feel free to call.
