Chris Brown RPT started work as a piano technician in 1977. A graduate of North Bennet Street School, he has worn many hats in his career: college technician, concert tuner, rebuilder, private customer piano-care provider, teacher. And more recently, he has designed and manufactured tools for the trade!

In 2005, Chris officially specialized in grand action regulation and rebuilding and started working on the tools and protocols that have become the Grandwork System. He assembled a team of experts to better provide both in-home care and full rebuilding services: Jude Reveley RPT on bellies and refinishing, Mike Morvan on keys, Rob Bushell on moves, and Yoshi Yoshizaki RPT and Xiaodan Liu RPT on tuning, repairs, and regulation touch-ups.
