At the age of 17, despite parental opposition,[3] she embarked on a stage career, joining the company run by the impresario couple María Guerrero and Fernando Díaz de Mendoza y Aguado.
However, Argentinian audiences were deserting live shows in favour of the new radio broadcasts, and a proliferation of rival theatres in Buenos Aires persuaded Larrabeiti and her husband that their future lay in Spain.
They joined the Teatro Infanta Isabel in Madrid,[3] where stage successes included their appearance in "The Bonires of St John" ("Las hogueras de San Juan" – 1930) by Juan Ignacio Luca de Tena.

By this time their daughter, Mari Carmen Díaz de Mendoza, had established her own career as a Madrid based actress.
