The Decision-makers

The brothers, Reto and Marco Sieber ran SIGA for 23 years. On 1st January 2014, they handed over management to the new CEO, Patrick Stalder. Reto and Marco will in future focus on strategic management of the company as members of the Board of Directors.

The change in management does not have any effect on the focus of SIGA. The company will remain a family-owned company with a long term business policy and its own corporate culture.
