TESARO INTERNATIONAL

In 2016, we founded our international headquarters in Zug, Switzerland, in the heart of Europe. A 30-kilometer (20-minute) train ride from Zurich, the Zug office is the hub of our international business, serving countries across Europe. Zug is recognized as a dynamic business location and is an international center for innovation and technology, especially in the life science sector.
