Sergei de Jonge began playing the guitar as a teenager in Toronto. While in college de Jonge was introduced to Jean Larrivée by his guitar teacher - this led to him leaving college to work in Larrivée's newly established workshop until 1971. de Jonge then went to work for Patt Lister in Collingwood until 1972 when he left to set up his own workshop in Toronto making guitars in the way he had been taught by Larrivée. He made mostly classical guitars until 1979 when he began building both steel and classical guitars. He continued building guitars while raising his family until he lost his workshop unexpectedly in 1986 and then went to work as a carpenter on film sets. in 1992 he set up a small home workshop on the Lakeshore in Toronto. In 1995 he began giving guitar making classes and has been making guitars continuously ever since. His children were constantly in and out of the workshop while they were growing up, some have now become luthiers in their own right.
