    In January 2017, the Columbus County board of commissioners voted to disengage from Eastpointe, and asked for permission to join Trillium. The Trillium Governing Board voted to accept this request on January 30, 2017. Columbus County complied with all the requirements to complete this realignment and on March 21, 2018, Secretary Cohen with the Department of Health and Human Services approved Columbus County’s request.
