At the 2015 ONA House of Delegates, transformational changes were made as part of Bylaws revisions that changed the Regions structure. These changes were a result of several years of work by ONA members. As a result, the Regions are transitioning from seven geographically based independent Regions to a more member-driven structure, of six Regions. This change is to encourage Regions and Members to develop smaller community based Chapters. A Region map is below indicating which counties are in each Region.
