Once seated at her front-row table, the ambassador was personally welcomed by pop sensation Konstantinos Argyros, who serenaded the crowd with his biggest hits. Sharing her table was billionaire Eric Vassilatos, whose private jet had whisked her to Greece earlier in the week, along with a few more people among her inner circle. At one point, a fellow guest invited Guilfoyle onto the dance floor — she obliged briefly before returning to her seat, later joining in enthusiastically on the traditional Greek Syrtaki and Kalamatiano dances, linking arms with guests in a circle to dance. The glitzy evening followed a much larger event at the Grand Hyatt, which drew more than 300 guests. By contrast, Sunday's celebration at the Athens Center was an intimate affair of around 150, attended by several leading figures from Greece's business and political circles, including Tourism Minister Olga Kefalogianni. Taking to the stage, Guilfoyle kept her message simple: 'I will not disappoint you.' But behind the glamour, her whirlwind start has already stirred murmurs in diplomatic circles. Before officially presenting her credentials to Greece's president — a required step before assuming her ambassadorial duties — Guilfoyle had already plunged into a full social calendar of receptions and late-night gatherings, many coordinated through the US Embassy's own channels. The high-octane debut, packed with photo ops and VIP appearances, hasn't gone unnoticed in Washington or among seasoned members of the foreign service community. The ambassador's busy weekend included an appearance at a 250th anniversary celebration of the US Marine Corps on Saturday night at a central Athens hotel. Guilfoyle is set to be formally received by President Konstantinos Tasoulas at the Presidential Palace on Tuesday, officially marking the start of her tenure. Later in the week, she'll attend the 6th Transatlantic Energy Cooperation Conference (P-TEC), alongside US Energy Secretary Chris Wright, Interior Secretary Doug Bergham, and more than 20 European energy ministers — marking her first official appearance at an international forum since taking office.
