Melanie O´Neill

Trainee – Die Opernliebhaberin

Im Rahmen ihres Musikstudiums an der Boston University absolvierte die gebürtige US-Amerikanerin im Frühjahr 2013 ein Auslandssemester in Dresden, das ihre Zukunft nachhaltig prägen sollte. Nachdem sie einige Jahre als Assistentin der künstlerischen Leitung in der Washington National Opera in Washington DC tätig war, fand Melanie, dass die Zeit reif für eine Veränderung sei. Also packte sie kurzerhand ihre Sachen und zog zurück nach Dresden. Bei HOLY TRINITY begann Melanie zunächst als Praktikantin, bis sie sich entschied, hier eine Ausbildung zur Kauffrau für Marketingkommunikation zu beginnen. Die neu erlernten Inhalte kann sie dabei gleichzeitig in eigenen Projekten im Unternehmen anwenden und vertiefen.

Auch wenn Melanie der Musik beruflich mittlerweile den Rücken gekehrt hat, ist die Oper nach wie vor ihre große Leidenschaft. Deshalb versucht sie, möglichst viele Stücke in anderen Ländern zu sehen – in verschiedenen Sprachen, mit verschiedenen Sängern, in verschiedenen Inszenierungen. Für Melanie ist das Schönste daran, dass sie nie die gleiche Vorstellung zweimal sieht.
