Dana Lanza
CEO & Co-Founder Confluence Philanthropy

Dana launched Confluence Philanthropy in August of 2009 after serving as the executive director of the Environmental Grantmakers Association (EGA). While at EGA, Dana provided networking services to over 250 grantmaking organizations from across North America and Europe. As director, Dana worked with the Rockefeller Family Fund, and led a then 20-year old EGA into an independent 501c3 organization. From 2009-2011 Dana served as the Program Director and Board Advisor at The Swift Foundation while launching Confluence.
Prior to Philanthropy, Dana founded Literacy for Environmental Justice (LEJ), an environmental education and youth empowerment organization for at risk youth. While there, she acted as a lead organizer in the closure of San Francisco’s infamous Hunters Point Power Plant; raising funds to supplant it with the region’s first off-the-grid educational Eco Center. In 2005, she contributed to Sierra Club Book’s anthology titled Ecological Literacy: Educating Our Children for a Sustainable World.
She has been a fellow at the Donnella Meadows Leaders Fellowship Program in Systems Theory and the California Women’s Foundation Policy Institute. Dana has also lived and worked among the Samburu people in northern Kenya for many years, the Cheyenne River Lakota in South Dakota, and Kosovan Roma refugees in Europe. Dana lives in Oakland California but is often also found in Brooklyn, NY.
