Billie Greenwood and her husband are retired educators now working as activists and volunteers. They divide their time between the U.S./Mexico border, where they focus on immigration and community development, and the Midwest where they work in the area of housing and homelessness. Their personal interests lie in the areas of economic and social justice, peace issues, and living voluntary simplicity. Billie also contributes regularly to The Sirens Chronicles, The Peace Tree and Allvoices.
