She came to Chile with the Méndez Company and later changed to another, which bore her name (to attract an audience, as she was not the owner), which performed in Valparaíso, at the Victoria Theater.

She worked alongside figures with deep roots in the bataclan such as Tito Lusiardo, Adriana Delhort, and Tita Merello.
