About Matthew J Bouillon
Matthew J Bouillon Mascareñas built a legal education that crosses languages and legal systems. He earned a J.D. from Boston College Law School (2010). Before that he completed a Master, Level I, in Human Rights and Humanitarian Action at Universita degli Studi di Siena (2006) and an A.B. in Romance Languages from the University of Georgia (2004). He also holds translation certifications from the American Translators Association for both Italian-to-English and Spanish-to-English work.
His early career placed him in New Mexico courtrooms. In 2011 he served as an assistant district attorney in the Eighth Judicial District of New Mexico. That prosecutorial foundation led to roles in state government focused on financial crime and securities oversight. In 2013 he joined the New Mexico Attorney General’s office to work on anti-money laundering matters, and by 2015 he was a senior prosecuting attorney in the New Mexico Securities Division.
He moved into a series of regulatory and policy posts after that. In 2017 he joined the Colorado Department of Law as an assistant attorney general in the Securities and Banking section. Two years later he returned to the New Mexico Securities Division as its director. Those positions gave him hands-on experience in investigations, enforcement and rulemaking related to securities and financial institutions.
Mascareñas has also worked in private practice and firm settings. In 2020 he practiced as a lawyer at Marrs Griebel, Ltd. He opened the Law Office of Matthew J. Bouillon Mascareñas, LLC and served as its principal in 2021. In 2022 he took on a senior counsel role at Industria Business Lawyers, LLP. The sequence shows a pattern of alternating public-sector enforcement work with private practice and advisory roles.
His professional profile reflects a mix of securities enforcement, banking regulation, white-collar investigations and cross-border language skills. The translator certifications in Italian and Spanish add an uncommon capability for cases or transactions that touch multilingual documentation or foreign counterparties. Colleagues and supervisors have placed him in leadership roles in government agencies and in senior positions at smaller firms.
He maintains a practice that draws on both his regulatory experience and his litigation background. He represents clients in matters that intersect securities law, banking regulation and investigations, and he advises businesses on compliance and transactional issues. His current practice focuses on securities enforcement defense, regulatory compliance, and related business law matters.
