Domestic Violence organizations?


I used to work for a national domestic violence advocacy organization in the US and would love to get involved in similar work here in Buenos Aires. Does anyone know about the services that are available for victims and their families? I'm used to the American model of non-profit shelters and agencies providing legal and social services for victims, but I don't know if similar services are available here or who provides them (non-profits, church agencies, local government, etc.). Just looking to learn and try to get involved if anyone has information. Thanks!
