Ruth Harmony
Fundraising Manager
Ruth graduated with her MBA in 2003 before spending 2 years with the Peace Corps in Guatemala, where she became fluent in Spanish. There, she worked with women and children in villages outside of Quetzaltenango, helping them start small businesses and writing a curriculum for financial self-management that she taught to 6th graders (the last year of school in those villages). All of the programs that Ruth implemented while there outlasted her, continuing at those same schools until the Peace Corps site closed. Since returning to the US, Ruth has worked in non-profit management and the government sector in various fields. She has a personal commitment to create access for people who are structurally excluded from resources and systems. Ruth lives in Kirkland with her two teenagers and many pets, and enjoys rock climbing and cooking in her free time.
