From 2002-2004, Kirstin Falk worked for the Washington, DC-based New Democrat Network (NDN), a national organization committed to pushing the Democratic Party (and American political attitudes generally) ever-farther to the left. Falk helped NDN update its technology and development infrastructure.
Falk also has worked for EMILY's List and the Planned Parenthood Federation of America. In addition, she spent four years in the private sector working in the field of portfolio management.
Today Falk is the Executive Director of the San Francisco-based New Progressive Coalition, founded by Andrew Rappaport in 2005 to help individual donors identify specific leftist organizations that are worthy of their financial support.
