Ms. Zubovic, lovingly called Duba by myself and her students, is a fantastic voice teacher and linguistics coach. I had less than six weeks to brush up five selections for my Masters in Opera audition for the University of Michigan, after taking a three year break from classical singing, and she was able to work me back into shape, cover all four classical languages, and prepare me for the audition. I was accepted to Michigan, UCLA and NYU after working with Duba, as well as taking first place in the Classical Singer Vocal Competition of 2014. Her technique is flawless and drive for perfection pushes students of all level to become stronger and better singers. Beyond technique and languages, her knowledge of the opera world, repertoire and continued connections to active singers with the LA Opera and more, make her a networking guru as she helps guide me into the next phase of my career. Other words that describe Duba are dedication, compassion, professionalism, intelligence, and kindness. Her summer program, OCAVA, is run just as professionally as her voice studio, opening Italy up to young artists each year that would not normally have the opportunity. I would recommend Duba to anyone in the Orange County area with confidence.
