Remembering Dar Wiekamp

Memorial recently witnessed the passing of one of its most ardent champions and strongest supporters. Darwin L. "Dar" Wiekamp. Dar was among a very select group of our most important community champions who have also left an enduring legacy beyond their own lives. That legacy arches over many aspects of our lives today.

The Wiekamps understood that "health" springs from all facets of human life. Their philanthropic support of Memorial's mission led them to provide core funding for Schwartz-Wiekamp Medical Group in Mishawaka. This center for family medicine now provides a medical home for many in the eastern end of St. Joseph County. For Memorial Children's Hospital, Dar and Dot generously supported their grandchildren, Jim and Julie Schwartz, by boosting the launch of Memorial's Developmental Pediatrics Program.

Memorial gratefully joins the Wiekamp family in celebrating Dar's long, full and meaningful life — meaningful to all who live here in their community
