The Columbus Easton Center occupies the entire second floor of a modern, brick-façade, four-story building and has an impressive reception area. Its location in Central Ohio's largest mixed space campus is one of the most prestigious areas for business. The center is minutes from interstate highway I-270 and Port Columbus International Airport. Columbus's diverse economy is based on education, insurance, banking, fashion, defense, aviation, food, logistics, steel, energy, medical research, healthcare, hospitality, retail, and technology. It is home to the world's largest private research and development foundation - the Battelle Memorial Institute - and to CAS (Chemical Abstracts), the world's largest clearing house of chemical information.
