Was one of the original 7 founding members of East West Players, the Asian American theatre company in Los Angeles formed in 1965, which is still in operation today. Along with Quo, founders include Mako (Artistic Director for first 23 years), James Hong, June Kyoto Lu (as June Kim), Guy Lee, Pat Li and Yet Lock.
Married name was originally 'Kwoh'. Changed spelling to 'Quo' because
people kept asking if the name was a radio station.
Was teaching sociology at a community college when she heard that
director Henry King was looking for a dialect coach for Jennifer Jones, who
played a Eurasian in the 1955 film Love Is a Many-Splendored Thing (1955). The director instead hired
Quo to play a small role in the film as Jones' aunt.
