He worked for six months in the office of the Executive Director of the International Monetary Fund in Washington DC, and then two years for the Commission of the European Communities in Brussels, Belgium. In 1982, he became President of Lux-Development, the company that runs the bilateral and intergovernmental program of development assistance to the government of Luxembourg. In addition, he serves as a director of Arcelor-Mittal and Banque Générale du Luxembourg. He serves as patron of the Luxembourg Basketball Federation and the youth section of the Prince Guillaume Municipal Band of the city of Differdange.
Prince Guillaume is married to Sibilla Weiller, a distant cousin. Sibilla is a descendant of Queen Victoria via her youngest child Princess Beatrice. She is a granddaughter of Infanta Beatriz of Spain and a second cousin of King Felipe VI of Spain. Guillaume and Sibilla were married first in a civil ceremony held on September 8, 1994, in Sélestat, France, followed by a religious ceremony on September 24, 1994, at the Versailles Cathedral (Cathédrale Saint-Louis de Versailles). The couple had four children:
- Prince Paul Louis of Nassau (born 1998)
- Prince Léopold of Nassau (born 2000, twin of Charlotte)
- Princess Charlotte of Nassau (born 2000, twin of Léopold)
- Prince Jean of Nassau (born 2004)
In September 2000, Prince Guillaume and Princess Sibilla were injured in a serious car accident in France. For a period of time, Guillaume was in a coma. Due to the accident and the prince’s condition, his father’s planned abdication as Grand Duke of Luxembourg, scheduled for September 28, 2000, was postponed until the first week of October.
Prince Guillaume and his family live in Luxembourg and are often in attendance at major events in the Grand Duchy, as well as most family functions.
