German American Chambers of Commerce

With headquarters in Atlanta, Chicago and New York, as well as branches in Detroit, Houston, Philadelphia, and San Francisco, the German-American Chambers of Commerce (AHK-USA) offers members and clients a nationwide service network. The three regions (Atlanta, Chicago, and New York) operate independently with their own management and board of directors. Since 2013, a superordinate board of directors has been formed, comprised of the three chambers’ presidents and the three chairmen of the board of directors from Atlanta, Chicago, and New York.
