Training

I have been making lutes and related early instruments since 1989 when I enrolled at the
London College of Furniture (now part of the London Metropolitan University). By the summer of 1994 had successfully completed five years of instrument making, study and research into the subject and attained a BSc. Hons.

Since leaving LCF I have continued instrument making to the high standard demanded by professional musicians and serious amateurs alike. After some time spent in the West Country I set up a permanent workshop in Kent in 1998 ~ still specialising in early instruments, though I have also made classical guitars and members of the mandolin family and have carried out numerous repairs to various types of stringed instruments.
