I am engaged in the maintenance, restoration and rebuilding of early keyboards (primarily harpsichords). I studied this craft with Gerrit Klop (1991, Holland) and Michael Scheer (1992, Germany). Over three decades, dozens of instruments have been repaired, restored or rebuilt, located in seven countries in Europe and the Middle East. The work on the instruments was summarized in a series of four articles, first published in the FoMRHI Quarterly (The Fellowship of Makers and Research of Historical Instruments, of which I became a permanent member in 1998 and a member of the Board in 2015).
