About Matt

Matt Bouillon Mascareñas is admitted to practice in New Mexico, Colorado, and Georgia. He is the founder and sole attorney at the Law Office of Matthew J. Bouillon Mascareñas LLC.

Matt began his career in the aftermath of the housing crisis as a local assistant district attorney in a two-lawyer office in northern New Mexico where he handled anything that came through the door. His first experience admitting expert testimony came in a poaching trial in which state Game & Fish agents matched the DNA from a gut pile to the meat seized from the defendant's freezer. His career has frequently taken turns that enabled him to learn something unusual or unexpected. In his next role as assistant attorney general assigned to the AG's anti-money laundering unit, he took on responsibilities well beyond other junior lawyers, leading the prosecutions of the "AZ boys" criminal enterprise for racketeering, money laundering, meth trafficking, and various other crimes. He eventually gravitated to securities regulation, first as the senior prosecuting attorney for the New Mexico securities division; then as an assistant attorney general in the Department of Law in Denver; and finally back to New Mexico as the securities division director. In 2020, he entered private practice and began working directly with clients in the construction industry. Like securities, he found construction to be an interesting and compelling area of law. In particular, he was surprised that such a vitally important industry was often overlooked by local practitioners.

Matt currently represents a Santa Fe-based contractor in Herrera v. RLD, a case challenging the Construction Industries Division's practices under the Civil Rights Act and Inspection of Public Records Act with far-reaching implications for New Mexico contractors.

This combination of deep familiarity with the state's regulatory apparatus and hard-fought litigation experience is what shapes his construction law offerings. He designed them precisely to serve an underserved industry. Reviewing an agreement is not just a matter of reading clauses. It requires understanding how New Mexico's Construction Industries Licensing Act interacts with the Prompt Payment Act, how indemnification provisions hold up under the state's anti-indemnity statute, and what actually happens when a project goes sideways and a contractor has to enforce or defend contract language in arbitration or in court. Matt has been on every side of those disputes.

He is fluent in Spanish and Italian and represents contractors across all CID license classifications statewide.
