Replying to @RGrynspan
This is the kind of leadership the UN needs: the courage to mediate, accept setbacks and try again—matched by the discipline to streamline mandates and make the institution more effective. Rebeca Grynspan is setting out a serious, pragmatic vision for a UN that acts with purpose.

Our member Rebeca Grynspan (@RGrynspan ) visited the Marianna V. Vardinoyannis ELPIDA Children’s Hospital (@elpida_official ) in #Athens. Meeting with children, families, healthcare professionals and the dedicated team of ELPIDA served as a powerful reminder that development is ultimately measured by the well-being, dignity and opportunities we create for people, especially the youngest among us. The legacy of Marianna V. Vardinoyannis continues to inspire hope, compassion and solidarity, demonstrating how dedicated leadership and philanthropy can transform lives and strengthen communities. At a time of global uncertainty, investing in children, health and human development remains one of the most important commitments we can make to future generations.
