Kimberly Farley will join Sound Transit as deputy chief executive officer, the regional agency announced this week.

Farley will occupy the position alongside present deputy CEO Mike Harbour until his scheduled retirement in 2019 before taking it over fully, according to a news release.

“I’m thrilled to be part of this dynamic agency, working with mission-driven professionals to help Sound Transit deliver the voter-approved vision,” Farley said. “The vision of developing diverse and robust transit options will ensure the Puget Sound region will remain vibrant and growing — it’s a once in a lifetime opportunity.”

Farley is rejoining the public sector after a three-year stint in private industry. She most recently founded Volition Group, a firm focused on helping clients deliver mega-projects; she was also a vice president for power utility firm AES.

As vice president of Pegasus Global Holdings, Farley worked on major projects like the Tappan Zee Bridge replacement in New York and a major hydroelectric project in Chile, according to the release.

In the public sector, Farley directed operations for Alaskan Way Viaduct replacement efforts, under the umbrella of the Washington State Department of Transportation. There, she managed the project’s budget and finance processes, environmental documents, and property acquisition. She previously worked on other mega-projects for WSDOT, the release said.

In her role at Sound Transit, Farley is expected to play a leading role in expanding the agency’s services.

“Kimberly brings precisely the right mix of talents to Sound Transit for this critical phase of our growth, with a deep reservoir of capital project experience spanning both the public and private sectors,” CEO Peter Rogoff said. “Her skills and accomplishments include proven management of collaborative, cross-functional teams, which will serve us well as we advance our culture of quality, accountability and inclusion.”
