Arvaniti began competing full-time on the SWATCH-FIVB World Tour in 2003 at the age of 18 with Thalia Koutroumanidou and qualified for a spot in the Athens 2004 Olympic Games where the Greeks placed ninth.
Arvaniti and Vasso Karadassiou ranked as Europe’s top team on the 2005 SWATCH-FIVB World Tour as the pair finished fifth in points. In addition, the pair captured the 54-country Confédération Européenne De Volleyball (CEV) continental championship in Moscow last August to clinch the 2005 point’s title. While Karadassiou was named the top women’s player for the 2005 season by the CEV, Arvaniti became the youngest woman (20 years, three months, 15 days) to win a SWATCH event. She and Karadassiou upset top-ranked Juliana Felisberta Silva and Larissa Franca of Brazil in the finals of the Norway Grand Slam event last July in Stavanger. Arvaniti and Karadassiou, who won two of four CEV events in 2005, combined for $166,500 in earnings.
