After the completion of her music studies, she signed her first record contract with CBS, which gave her the international hit "Fill me up" and offered her the chance of an international career at a very young age. Mando remained in America for five years where she took up vocal training with Hal Sheaffer (vocal trainer of Barbra Streisand and Liza Minnelli) and interacted with many musicians, producers and with people who helped her talent grow. Her diverse knowledge and international edge defined her as the Greek artist with the international voice. Vangelis Yannopoulos, an A&R manager with record company Minos EMI heard of all these assets and signed Mando for her first album with the company that she stayed with for six successful albums: Dos mou ena fili... Afto to kalokeri" (Give me a kiss... This summer), "Ptisi gia dio" (Flight for two), "Kinisi triti" (Third move), "Esthisis" (Senses), "I diki mas I agapi" (Our love), and "Anisiho vlema" (Uneasy look).
