Proximity to Washington, D.C.'s national and international decision makers and to New York's financial markets make Maryland an attractive location for headquarter facilities. Other factors critical to a headquarters operation are the state's advanced telecommunications and extensive transportation networks. Outstanding airports served by numerous national and international carriers and a strategic U.S. eastern time zone allow Maryland companies to capture emerging business opportunities worldwide.
Maryland is home to industry leaders in key sectors such as aerospace and defense, electronics and fiber optics, biotechnology, information technology, financial services, and technology-driven manufacturing.
