Northeast Georgia Health System is closing its child care center in May, the hospital announced Wednesday to employees. The center has been open since 1967 and was serving about 80 families, or 102 children, including those in its after-school program. That accounts for about 2 percent of the health system’s employees, according to Carol Burrell, NGHS president and CEO. “This was a very difficult decision for our senior leadership team to make, and one that was only made after months of research and due diligence,” Burrell said in a news release.
