Alexander Flores

Alexander F. Flores is Senior Counsel at Singleton Schreiber’s New Mexico office, where he focuses on mass tort claims, wildfire litigation, catastrophic personal injury and wrongful deaths, and cases under the Federal Tort Claims Act (FTCA), including litigation in the U.S. Court of Claims. With a distinguished career as a federal prosecutor and military officer, Alex brings extensive experience in high-stakes litigation, having completed 17 federal jury trials. He is dedicated to advocating for justice, particularly in complex criminal and civil cases, and has a proven track record in both the courtroom and in legal leadership.

Prior to joining Singleton Schreiber, Alexander served as a Supervisory Assistant U.S. Attorney with the U.S. Department of Justice in Albuquerque where he led a team of prosecutors handling violent crime cases, including homicides, sexual assaults, kidnapping, and firearms offenses. He also specialized in Indian Country crimes, working to improve public safety in New Mexico’s Native communities. Alex forged deep relationships with Tribal leaders and law enforcement, and helped the Department of Justice to increase training, strengthen inter-governmental relationships, and improve the tempo and quality of investigations and prosecutions of crimes with a focus on Mission and Murdered Indigenous Persons and sexual assault cases. Prior to his appointment as a Supervisor, Alex personally prosecuted nearly 200 federal felony cases, including successful outcomes in appeals to the United States Court of Appeals for the Tenth Circuit.

Alex’s military experience further complements his legal expertise. He served twelve years in the United States Marine Corps, holding several key positions, including in the Office of the Chief Prosecutor of Military Commissions, as a prosecutor in Okinawa, Japan, an Aide-de-Camp, acting supervisory prosecutor, and complex trial prosecutor for all Marine units in the western U.S., where he led high-profile, special victim, and other significant cases. After transitioning to the reserves, he served as a law of war instructor, a supervisory prosecutor for the Department of Defense’s busiest prosecution office, and an administrative separations board hearing officer. In late 2024, Alex joined the New Mexico Air National Guard, where he now serves as Deputy Staff Judge Advocate, advising Wing leadership on military justice, operational law, and ethics, and ensuring compliance with the Uniform Code of Military Justice. Earlier in his career, he clerked for New Mexico Supreme Court Justice Edward L. Chávez—an experience that further refined his ability to navigate complex legal matters with discipline and strategic insight.

In addition to his legal practice, Alexander is actively involved in community and legal service organizations. He serves as a trustee for the Albuquerque Community Foundation, a Commissioner for the New Mexico Access to Justice Commission, and as a New Mexico Supreme Court appointee to the Access to Justice Fund Grant Committee. He is also a former Vice President of the New Mexico Hispanic Bar Association and has held leadership roles in various local organizations. Alex’s awards and recognition over the years include being recognized locally by Albuquerque Business First as the single “Most Outstanding Under 30” honoree in its annual “40 Under Forty” awards in 2013, and nationally as a Top Lawyer Under 40 Honoree by the Hispanic National Bar Association in 2021. 

Alexander earned his Juris Doctor from the University of New Mexico School of Law, where he was recognized with both the Dean’s Award and Faculty Award. He also holds a Master's in Public Affairs from Princeton University and a Bachelor of Arts in Public Policy and Political Science from The George Washington University.
