By MELISSA PATRICK | Kentucky Health News A collaboration of 31 grantmaking organizations across Kentucky have launched an initiative to focus on statewide policy changes to prevent and lessen the impact of childhood trauma, also called adverse childhood experiences, or ACEs. Barry Allen, president and treasurer of The Gheens Foundation, one instigator of the Bloom Kentucky coalition, said it will move grant- making organizations from across the state out of their comfort zone and into actively advocating for policy changes to prevent and reduce ACEs.
