Ken Allen is not a typical business leader.

To some, he’s ‘The Turnaround Guy’. For others, he’s ‘The Customer Champion’. In China, he’s ‘The Singing CEO’. To his people everywhere, he’s simply, ‘Ken’. Between 2010 and 2020, Ken Allen was the Global CEO of DHL Express – the world’s leading logistics provider and a household name in practically every country on earth.

But the story of DHL’s near collapse in the first decade of the 21st Century, to its transformation to an International mega-brand is also the story of a visionary business leader who cut through the hubris and rebuilt a corporation from the ground up.
