Meet The Arabella Team

Marissa Guerrero

Director

Marissa Guerrero advises clients and oversees projects on strategy development and evaluation. She brings extensive research experience and a passion for facilitating engaging and productive discussions to all of her work. Her current projects include learning partnerships focused on increasing evidence-based decision making in county and state governments and combatting domestic human trafficking. She also builds the capacity of foundation staff members and grantees to develop outcomes and indicators to track their progress toward goals. Though her strategy engagements are wide-ranging, much of her work at Arabella has focused on early education.

Prior to joining Arabella, Marissa was the resource development manager at the California Court Appointed Special Advocate Association. In this role, she partnered with the CEO and board of directors to create and implement the organization’s fund development plan. She also managed and evaluated initiatives to strengthen advocacy for California’s foster children, particularly focused on supporting young adults and LGBTQ+ youth in care.

For more than a decade, Marissa has worked with low-income and systems-involved youth to help them graduate high school; matriculate to college; and develop as writers, researchers, and advocates. She has taught gender studies, social theory, and graduate research colloquia at the University of Chicago. She graduated magna cum laude from the University of California, Los Angeles with a BA in political science and women’s studies. She also holds a PhD in political science from the University of Chicago, where she specialized in American politics and research methodology.

In her spare time, Marissa serves on the board of California Youth Connection, a youth-led organization that develops leaders who empower each other and their communities to transform the foster care system through legislative, policy, and practice change. She is also on the leadership team of Horizons Young Professionals for Equality (HYPE), a giving circle of LGBTQ+ young professionals in the Bay Area.
