Matt D'Ambrosio started working at Mandolin Brothers in Staten Island as a teenager in 1989. He witnessed first hand the boom in the vintage instrument market in the 1990s and had a great opportunity to learn about the building and repairing of instruments. During this period he also studied luthiery with Carl Thompson, Flip Scipio and John Motellone. In 1998 D'Ambrosio went to work for Guild in Westerly, Rhode Island starting with consumer repair work and eventually doing full rebuilds. In 2001 he opened his own workshop in Pawtucket, Rhode Island where he repairs and restores vintage instruments as well as specialising in making archtop guitars.
