Premier Health has approved plans for a new $28 million expansion project at its Good Samaritan North Health Center. The project calls for a 96,000-square-foot expansion at the center — at 9000 North Main St. — to include a 22-bed emergency department. The project is expected to create 80 jobs. The project first came to light late last month, with the hospital seeking economic development, or ED/GE, funding from Montgomery County.
