Howard County Executive Calvin Ball joined the National Pan-Hellenic Council of Howard County to celebrate the reopening of the High Ridge Center in Ellicott City, creating what officials say may be the first facility in the nation to house all Divine Nine organizations and Sigma Pi Phi Fraternity, Inc. under one roof. The renovated 21,000-square-foot building will serve as a hub for service, leadership and collaboration, while continuing to house Head Start programs on its lower level.
