Helping local and regional businesses expand to an international market is the name of the economic-development game, World Trade Center Savannah representatives told Hinesville Rotary Club members Tuesday.“Our mission is to create jobs and attract investment,” said Brynn Grant, chief operating officer for the Savannah Economic Development Authority and vice president of World Trade Center Savannah. Grant, a Hinesville native, said WTC Savannah was established in October 2011 to help area businesses and manufacturers grow globally, to identify foreign investment opportunities for the coastal Georgia region and generate the revenue to support these activities. Grant and her colleague, Leigh Ryan, WTC Savannah director of trade services, both spoke at the club’s meeting.“Ron Tolley, Anna Chafin and Liberty County were with us the entire time,” Grant said, referring to the Liberty County Development Authority’s role in supporting the creation of WTC Savannah.
