is Sacramento County Woman of the Year

Susanne T. Stirling

CalChamber Vice President for International Affairs Susanne T. Stirling has been recognized for her leadership and decades-long commitment to promoting economic development and cooperation between the state and other countries. In March, she was named Woman of the Year for Sacramento County by Senator Bill Dodd (D-Napa).

“In many ways, California’s economy is tied to international markets, and Susanne brings a level of experience and knowledge that is critical as we successfully and safely reopen our state,” Sen. Dodd said. “She has been an ambassador for international trade for many years and has continued to serve with distinction as we weathered this historic public health crisis. I’m proud to recognize her for her efforts to help our state’s business community.”

“I am deeply appreciative to Sen. Dodd for this recognition,” Susanne Stirling said. “During this challenging time in our world with global-wide trade disruptions, my focus is to assist with the state’s economic recovery on behalf of the CalChamber through our international ties. International trade is a major part of the economic engine that benefits businesses, communities, consumers and our state’s prosperity.”

Stirling is an appointee of the U.S. Secretary of Commerce to the National Export Council and serves on the U.S. Chamber of Commerce International Policy Committee and the California International Relations Foundation.

Previously, she was an appointee of Gov. Jerry Brown to the California International Trade and Investment Advisory Council and served on the board of directors of the International Diplomacy Council, the World Affairs Council of Northern California, the Danish-American Chamber of Commerce, and the Chile-California Council.

In November 2019, she was presented with the Outstanding Woman of the Year in International Trade award by the Women in International Trade, Los Angeles.
