Carlos became the national coordinator for the United We Dream Network, the first immigrant youth-led national organization in the United States. He led the organizing and campaign efforts that took the network from a loose, 7-member coalition to a 52-member organization organized by regions in 30 states. Most recently, Carlos was key in organizing the End Our Pain and Right to Dream Campaigns (2011-2012) that led to the victory of legal relief for 1.7 million undocumented youth. At age 26, Carlos has trained over 4,000 people in the arts of organizing and social change in 20 states.
