Summa Health System and a group of Medina-based doctors plan to build an outpatient surgery center and physician offices in Medina, OH. Construction on the 75,000-square-foot building, which will also house diagnostic testing and other outpatient services, is expected to begin late this summer. It will be completed in about 14 months. The center will be built on Ohio 18 on 10 acres straddling Medina and Montville Township. Summa and NorthEast Ohio Management Service Organization have an additional 20 acres for future development.
