Frau Valeria Mazza arbeitet für unser Unternehmen als Freelance-Übersetzerin für die Sprachenkombination Deutsch – Italienisch. Sie hat sich sehr rasch in die Terminologie und das Themengebiet unseres Hauptkunden eingearbeitet und liefert stets exzellente Qualität.
Ihre Arbeitsweise ist präzise, und sie stellt sich stets flexibel auf die Lieferwünsche unserer Kunden ein, auch bei größerem Volumen. Wenn Rückfragen auftreten, ist Frau Mazza immer zu erreichen. Ich habe Frau Mazza als gewissenhafte, zuverlässige und sympathische Übersetzerin kennengelernt und kann sie nur weiterempfehlen. Unsere Kunden sind auch sehr zufrieden mit Frau Mazzas Übersetzungsqualität.

We are satisfied with Valeria’s services since 2004.


It was a pleasure to work with her, as she is not only very responsive and quickly gets the idea of what the client expects, she also delivers very good translations and accurate revision projects. Valeria is always very professional, which makes it pleasant to discuss no matter which aspect of an assignment with her. I highly recommend her as a translator and/or proofreader and hope to have the pleasure to work with her again myself.
