Quick Facts

From Family Roots to Global Influence

Ernesto Bertarelli’s journey began under the weight and promise of a family legacy. Born in Rome and raised partly in Switzerland after his family relocated in 1977, he was shaped early on by both Italian heritage and Swiss stability. 

He studied at Babson College (graduating 1989) and later earned an MBA from Harvard Business School in 1993.  These formative years laid the foundation for a business philosophy blending bold innovation with disciplined management.

In 1996, Bertarelli became CEO of Serono, the family’s pharmaceutical company, and two years later inherited it, alongside his sister, following his father’s death.  Under his leadership, Serono underwent a dramatic transformation — shifting from traditional pharmaceuticals to biotechnology, vastly expanding its scope and profitability. By 2006, revenues had multiplied several times.
