    Parents and Caregivers of BIPOC Children (Zoom)

    AC Parent/Caregiver Affinity Groups are designed to facilitate the following:
    • Discuss issues that support AC's diversity, equity, and inclusion goals and priorities
    • Hold space to identify issues relevant to and through the lens of group participants 
    • Build capacity for cross group dialogue and more inclusive spaces
    • Connect issues relevant to the groups to the larger community
    The affinity groups are not intended to imply that all families share the same experience. Rather, the groups provide the opportunity for reflection, dialogue, and support, and the capacity to build more inclusive spaces.

    This meeting will take place via Zoom.
