Geneva Amateur Operatic Society


The Geneva Amateur Operatic Society is an English-language musical theatre company that began as a light opera group. It also has performed a pantomime nearly every year.
Based in Geneva, Switzerland, GAOS was founded in 1971 by a small group of musical theatre enthusiasts. They produce about three productions per season, including their traditional Briish-style pantomime in the winter. GAOS is a nonprofit organization, its members receive no payment, and the society gives substantial donations to various charities around Geneva.
