Kimberly Guilfoyle sworn in as first woman U.S. Ambassador to Greece: A new chapter in American–Hellenic Relations.

Friends and family from the D.C. area and Florida were there to see her at the under-radar event, including Guilfoyle's son who held the Bible during the ceremony.

As a source told British publication Daily Mail: 'She was very excited to be the first female ambassador to Greece. Everyone was laughing and joking with her. She was very personable and was in great spirits. She even joked about brushing up on her Greek dancing skills.'

Many state department staff affiliated with Greece were also in attendance, like Gray Harker, who used to work for Senator Ted Cruz.

Michael Kratsios, who served as the 13th director of the White House Office of Science and Technology Policy was also in attendance along with Christos Marafatsos, chairman of Greek Americans for Trump was present.

He has reportedly been her 'sherpa' and by her side helping her throughout the entire process.

Jennifer Wicks, the director of the office of presidential appointments, swore her in today.

As for where she goes next, Guilfoyle's next move is where most vacation, but a source close to the new ambassador says she is ready to start working.

Background

On September 18, 2025, the United States Senate voted 51–47 to confirm Kimberly Guilfoyle as the U.S. Ambassador to the Hellenic Republic (Greece). She is expected to arrive in Athens later in October, to present her credentials and assume official duties. The former prosecutor and media personality pledges to strengthen U.S.–Greece ties through diplomacy, defense, and energy cooperation.

Her appointment comes at a moment of renewed strategic interest in Greece and the Eastern Mediterranean region: energy, security, and diplomatic engagement are all rising priorities. As the first woman to hold the U.S. ambassadorship in Greece, Guilfoyle now steps into a role that demands both finesse and vision. (Wikipedia)

Background & Political Context

President Donald Trump first announced the nomination in December 2024, praising Guilfoyle’s “extensive experience and leadership in law, media, and politics” and citing her suitability to enhance U.S.–Greece relations in areas such as defense, trade, and innovation.

Guilfoyle’s career prior to diplomacy has largely been in law, media, and political organizing. She is a former prosecutor and ex–Fox News host, and more recently has been active in Republican campaign fundraising. (Wikipedia) Her path to an ambassadorship thus depends in large part on her ability to quickly pivot from domestic political work to the demands of diplomatic statecraft.

Her appointment also follows the tenure of George James Tsunis, who served as U.S. Ambassador to Greece from 2022 to 2025 under the prior administration. (Wikipedia)

Priorities & Areas of Focus

Although Ambassador Guilfoyle has not issued a detailed strategic blueprint yet, signals from her nomination statements and public remarks suggest several policy areas where she intends to concentrate her efforts:

1. Defense, Security & Regional Stability
   U.S.–Greece cooperation already intersects heavily in defense and security, especially with Greece’s strategic position in the Eastern Mediterranean and NATO’s interest in the region. Trump’s nomination announcement explicitly cited “defense cooperation” as a core pillar of Guilfoyle’s mission. (The American Presidency Project)She is likely to deepen collaboration on maritime security, intelligence sharing, monitoring of Turkish–Greek tensions, and coordination on regional defense initiatives.
2. Energy & Climate Diplomacy
   Greece is becoming a hub of energy interest in Europe and the Eastern Mediterranean—especially as new pipelines, LNG infrastructure, and renewable energy projects are under development. Guilfoyle’s arrival aligns with a transatlantic energy and climate summit (P-TECC) held in Greece, underscoring that the U.S. sees this country as central to its regional energy strategy. Strengthening energy partnerships, encouraging sustainable investments, and steering Greek–U.S. cooperation on clean‐energy transitions may be some important components of her agenda.
3. Trade, Investment & Economic Innovation
   From her nomination announcement to media commentary, pushing U.S.–Greece economic ties is a recurring theme. The Trump administration framed her role as advancing “trade and economic innovation” between the two countries. (The American Presidency Project) Expect Guilfoyle to emphasize American business engagement in Greek infrastructure, tech, tourism, and possibly defense procurement.
4. Public Diplomacy & Soft Power
   In a country with a rich cultural heritage and significant diaspora communities, the soft power angle will matter. Building cultural, educational, and people‐to‐people links—especially with Greek Americans—could serve to amplify U.S. influence and foster goodwill.
5. Upholding U.S. Foreign Policy & Rule of Law
   During her Senate confirmation hearing, Guilfoyle was asked about Greek–Turkish maritime tensions and international maritime law. She declined to make sweeping commitments but pledged to defend U.S. allies (i.e. Greece) and follow instructions from the State Department and the President. (Wikipedia) Her approach to legal and security disputes in the region will thus need to balance diplomatic neutrality, alliance obligations, and U.S. strategic interests.

Challenges & Expectations

Guilfoyle’s transition will not be without hurdles. She enters the diplomatic field without prior foreign service or Ambassadorial experience, which raises questions about her ability to handle the complex geopolitics of the Eastern Mediterranean. Analysts may watch closely how she navigates Greek–Turkish tensions, energy disputes, and regional alliances.

Moreover, her past remarks—most notably a 2015 comment about Greeks being “freeloaders” in reference to economic bailout negotiations—have resurfaced and drawn scrutiny. (Wikipedia) She will need to rebuild credibility in Greece and demonstrate sensitivity to historical and contemporary Greek perspectives.

Still, her confirmation signals that the U.S. aims to engage Greece more robustly in its broader strategic calculations, viewing Athens as a key partner. If Ambassador Guilfoyle can deliver on deepening ties in security, energy, trade, and culture, her tenure might mark a high-profile pivot in U.S.–Greece diplomacy.
