Andrea fell in love with organizing as a student activist. Upon finishing college, she jumped headfirst into the worker rights movement, organizing in communities throughout the country. As a lead organizer for a union, Andrea led numerous successful campaigns to unionize employees. She recently served as a board member for Next Generation, which prioritizes grassroots organizing using technology and innovative methods to mobilize younger union members.

Andrea is a proud graduate of the Challenging White Supremacy Program aimed at white activists committed to anti-racist movement-building. In 2019, she graduated from PGS with a Dual MPA/MBA in Sustainable Solutions, also serving as a Spiekhout Fellow for Civic Leadership and Social Justice. Andrea has worked with non-profits, labor, and philanthropy and has consulted on various projects at the community-building and policy level. She is fiercely committed to social justice. Andrea believes systemic change requires centering those most impacted, while simultaneously grappling with and addressing the ways that misogyny and supremacy play out in organizations, in ourselves, and in movement spaces.
