Born in Buenos Aires, she completed her classical dance training in her native Argentina: Julieta studied at the National Dance Academy "Maria Ruanova" as well as at the School of Art of the "Teatro Colón". She received scholarships from the Ballet Hispánico and the Jennifer Muller Dance Company in New York.

Afterwards Julieta moved to Germany: Here she danced in several ballet companies: Staatstheater Wiesbaden, Pfalztheater Kaiserslautern, Stadttheater Görlitz and at the "MDR Deutsches Fernsehballett" in Berlin. Her first musical engagement was "Aida", followed by "Die schöne und das Biest", "Miami Nights", "West Side Story", "Jesus Christ Super Star", "Der Schuhe des Manitu" and "Ich war noch niemals in New York". As a tango singer, the artist had embodied the main role of "Maria" in the British premiere of the Piazzolla tango operita "Maria de Buenos Aires" and she was invited to sing live for it by BBC London.
