Hector Carreon is the head of the NOA and founder/editor of La Voz de Aztlan ("The Voice of Aztlan"), an Internet "news service" which debuted in January 2000. According to the La Voz de Aztlan, "Hector is a graduate in Civil Engineering from California State University at Long Beach where he was a founding member of the Society of Mexican-American Engineers and Scientists (MAES). He served honorably for two year [sic] as a Vietnam-era soldier in the U.S Army's 2nd Armored Division and is a graduate of the Mexican-American Legal Defense and Education Fund's Advanced Leadership Program."

Carreon may have been introduced to Hispanic nationalism during his time with the Brown Berets, a group that came into existence in 1967 in Los Angeles soon after the Black Panther Party was founded in Oakland, California. Similar to the Panthers in organization and ideology, the Brown Berets focused on the mobilization and unification of "Chicanos for Self Defense" against police brutality, with a strong emphasis on youth in the "Barrios" and on education.

La Voz de Aztlan and the group’s e-mail service are published from Los Angeles; staff writers include Miroslava Flores and Ernesto Cienfuegos. In fall 2001, the group described plans to improve its Web site: "Shortly we will be implementing more advanced Internet technologies that will enable us to reach more people in a more efficient way. We also plan to add more sophisticated audio and video capabilities to the website." In addition to the anti-Semitic nature of NOA, the group has posted several virulently homophobic articles editorials and articles on its Web site.
