A SWN spokesperson said that employees would use the weekend to move into the LEED-certified, 100,000-square-foot, $25 million facility, so that business there may begin Monday. The regional headquarters building, located at the Village at Hendrix, may occupy as many as 500 employees. COURTNEY SPRADLIN PHOTO
