Sergio was born and raised in Tucamon, Argentina. He lived there with his family until they were forced to leave under death threats from the military government in 1976 (during an era known as “the Dirty War” in Argentina). Sergio and his entire family left the country with only the clothes on their backs and sought asylum in the United States. Sergio’s grandfather, Jose Siderman, sued Argentina for human rights violations and the theft of his properties, becoming the first immigrant to successfully sue a foreign sovereign nation from the United States (see Siderman v. Argentina, 965 F.2d 699 (9th Cir. 1992).
