Tiffany Washington is a senior public-sector executive with more than 15 years of experience advising top elected leaders and directing large, complex organizations in highly accountable environments. Most recently, she served as Chief Deputy Mayor for the City of Seattle, acting as the primary advisor to the Mayor and exercising delegated authority over policy, operations, budget management, and crisis response. In that role, she helped co-manage a $7 billion biennial budget and translated mayoral and council priorities into coordinated, citywide action.

Her career is marked by executive leadership, governance support, fiscal stewardship, and a commitment to organizational performance — all grounded in equity-centered policy and community-focused outcomes. She has previously held key leadership roles as Deputy Director within the Seattle Department of Human Services and Deputy Director at the Department of Education and Early Learning, where she contributed to transformative initiatives including Seattle Promise and Seattle Youth Employment.

Before joining the City of Seattle in 2015, Tiffany served as Vice President of Programs at Big Brothers Big Sisters of Puget Sound and as Director of Youth Programs at the Mockingbird Society, an advocacy organization supporting foster youth across Washington. Her passion for racial, educational, and economic justice is rooted in her early work as a youth outreach worker in Seattle’s Central District. Throughout her career, Tiffany has demonstrated sound judgment, discretion, and the ability to lead through complexity while maintaining public trust. She is highly regarded for her experience collaborating with elected officials, boards, senior leadership teams, and cross-sector partners.

Leadership and the Selection Process

In her role as Deputy City Manager, Washington will help lead the day-to-day operations of the City and work closely with department directors to ensure that City priorities are carried out in a coordinated, effective way. She will play a key role in helping SeaTac deliver on the goals set by the City Council and the community, while strengthening how the organization works together internally.

“Tiffany’s demonstrated ability to lead complex organizations, support teams in delivering meaningful results, and maintain public trust in fast-paced, complex environments make her exactly the kind of leader SeaTac needs as we continue to grow and evolve as a City,” said City Manager Jonathan Young.

The Deputy City Manager position was filled through a deliberate, values-aligned selection process led by City Manager Jonathan Young. Candidates were evaluated based on the City’s enterprise values — social responsibility, emotional intelligence, accountability, trustworthiness, and collaboration — as well as their ability to lead complex organizations and advance strategic priorities.
