Melanie Kreis, born in 1971, attended the State University of New York at Stony Brook,, and graduated in 1994 with a master's in physics and obtained another degree in physics in 1997 from the University of Bonn. In 2000 she graduated with a Master of Business Administration at INSEAD, France. Kreis began her career in 1997 at the management consultancy McKinsey & Company in Cologne. In 2000 she then moved to Apax Partners, based in Munich and London. She has been working for Deutsche Post DHL since 2004 and was appointed to the board in October 2014. Kreis, in her fourth year as CFO of the German postal service, is the only woman on the group’s six-person executive board that oversees half a million employees. In a fiercely competitive courier market, Deutsche Post DHL posted its highest operating revenue of all time in 2017 at $3.7 billion. As CFO, Kreis has been key in leading the investment agenda of the group and the company’s adoption of new accounting standards ahead of competition. This past year, the group streamlined its portfolio and strengthened its focus on logistics, in part, by selling Williams Tea Lag, a provider of marketing and communications supply chain services.
