Dubravka Zubovic was born in Zagreb, Croatia. Within a short period of time, Dinko Fio, the chorus conductor at the Croatian National Radio/TV, discovered her as a young prodigy, so she began her voice studies at the early age of 14.
After graduating from Zagreb Academy of Music with a B.A. degree (Vladimir Ruzdjak, a renowned baritone, was her voice teacher), Dubravka became a leading mezzo-soprano of Belgrade Opera, Serbia (former Yugoslavia).
In 1977 Ms. Zubovic graduated with an M.A. degree in Music from Belgrade University, in the class of Anita Mezetova. After that, Dubravka studied at Teatro alla Scala di Milano (Centro di Perfezionamento), one of the most prestigious opera houses in the world, with Gina Cigna and Ettore Campogalliani (voice teacher of Pavarotti, Mirella Freni), Mo Beltrami and Mo Pastorino.
During her carrer, Dubravka's long time mentor was a distinguished soprano Zinka Milanov.
