Genco, one of America’s largest third-party logistics providers, is relocating its headquarters from Blawnox to Cranberry Woods business park. It plans to move more than 300 employees to the 100,000-square-foot building, formerly used as a Verizon Wireless call center, this September. The company, which is was acquired by Federal Express last year, said the move was needed to accommodate its expansion. The building it is moving into is owned by McKnight Realty Partners. Verizon vacated its Cranberry facility in 2014.
