Grantee highlights
The Avantor Foundation works with a number of worthy organizations around the world. We partner with each grantee to ensure that their program aligns with our mission and offers an opportunity for Avantor associates to engage in volunteerism.
Mobilizing care for those in need

For the past 35 years, Stiftung Sozialwerk Pfarrer Sieber has been dedicated to helping people in need in Zurich, Switzerland. This organization is making a difference by providing emergency shelters, social counseling and medical care, among other services, to members of the community.
In 2024, the Avantor Foundation supported the “Sieber-Mobil,” a mobile version of their care center. This initiative is designed to reach people who live in precarious situations or are unable to visit a medical or counseling facility. The Sieber-Mobil extends Stiftung Sozialwerk Pfarrer Sieber’s services to more people in need, serving them with the care and dignity that everyone deserves. This partnership is our first in Zurich, expanding our reach to more communities in which we operate.
