Community members help guide cancer research at Holden through our Community Advisory Board.

The Holden Community Advisory Board (CAB), comprising Iowans with diverse identities, backgrounds, and experiences, was established in 2019. The CAB serves as the communities’ voice with respect to cancer research at Holden.

CAB members participate in quarterly meetings to provide guidance to leaders and learn about research efforts at Holden. CAB members are actively involved in reviewing seed grant proposals, writing letters of support for researchers, and identifying priority areas for Holden research.
