Lor Holmes (she/they)

Independent Consultant and Community Organizer

Lor Holmes dropped out of college and worked as a school bus driver and community organizer in Boston before earning a master’s degree in Community Economic Development. Lor is a lifelong practitioner driven by passion for anti-racist social, economic and environmental justice.  Her life’s work has been in building innovative responses and demonstrating equitable solutions that serve people and communities.

At the Elizabeth Stone House in Roxbury, Lor started Boston’s first micro enterprise program, supporting low income women’s financial self determination. Then, as founding director at Harbor Communities Over Violence (HarborCOV) in Chelsea, she worked with immigrant communities to develop the country’s first permanent housing and economic development center for families affected by domestic violence. Lor has developed campaigns to address institutional and community racism and taught postgrad courses at Springfield College. Following the 2008 economic collapse Lor helped launch the S.U.N. Program, which enabled thousands of families to save their homes from bank foreclosure.
In Dorchester, Lor worked with low income community members to establish CERO Cooperative, a worker owned business providing commercial composting services to institutions and the food industry in Greater Boston. CERO provides good green jobs and rescues millions of pounds of food waste from landfill and incineration, instead to be re-eathed as compost, mitigating carbon pollution, revitalizing soil and supporting urban agriculture.

While Lor keeps pushing composting, circular zero waste economies and affordable housing, she strives to center family & friends, new adventures and singing with her community chorale.
