Our Firm follows a long-established tradition that began in the late 19th century when Demetrio Petra graduated as Attorney-at-Law and Doctor of Jurisprudence at Universidad de Buenos Aires (UBA). Many years later he was appointed Justice of the Supreme Court of Justice of Mendoza in recognition of his brilliant career.

His grandson, Julio Demetrio Petra graduated from Universidad Nacional del Litoral in 1971. Julio Demetrio Petra practiced law uninterruptedly until 1993. He established his own practice and worked as an outside counsel to major Mendocinian companies like Carbometal S.A. and Cristalerías de Cuyo S.A., focusing on employment, business, and civil law. In addition to this, he held important public offices. He was Solicitor General in the Department of Justice of the Province of Mendoza and then Federal Judge of the Federal Court of Appeals from 1993 to March 2012, when he retired. At present, Julio Demetrio Petra is consulting-partner at PETRA CREMASCHI ABOGADOS.
