Caduceus Society Chair

The Caduceus Society is a philanthropic guild of our CentraCare Foundation open to central, west-central, and southwest Minnesota practicing and retired physicians or dentists who make a gift to support the Foundation’s mission of improving health and health care.

Active membership in the Caduceus Society is achieved with an annual gift to the Foundation. Legacy memberships begin at $10,000 of cumulative giving. Caduceus Society members are invited to La Gratitude, the annual CentraCare Foundation donor recognition event.

Caduceus Award Recipient

Dr. Tilstra receives 2024 Caduceus Award

Geneticist David Tilstra, MD, CentraCare – Plaza Clinic Genetics, was presented with the Caduceus Award on May 9, 2024. This award recognizes the outstanding work of CentraCare physicians who exhibit humanitarian medical efforts locally or around the world.

Dr. Tilstra was nominated because of his work with the health care system and the community, which goes well beyond what is typically considered health care.
