About Mario Hoang
Mario Hoang Nguyen built his early legal identity inside clinic walls and litigation firms. While still a law student he served as S.J.C. Rule 3:03 Counsel for the Harvard Legal Aid Bureau in 2015. That role placed him in direct client representation under court supervision and exposed him to courtroom practice at an early stage.
The summer of 2015 brought a stint as a summer associate at Lieff, Cabraser, Heimann & Bernstein. There he worked on aspects of complex civil litigation and mass tort matters alongside seasoned litigators. The experience bridged student clinics and large-firm practice and offered a view of case development from intake through discovery.
He joined Locke Lord LLP as an associate lawyer in 2017. At Locke Lord he handled litigation assignments and contributed to trial preparation, motions practice, and client counseling. The files he worked on included commercial disputes and regulatory matters. Colleagues recall him as methodical and attentive to procedural detail. He spent several years developing case strategy and courtroom materials for trials and hearings.
In 2020 he added teaching to his resume, accepting a role as an adjunct professor of law at Texas A&M School of Law. In the classroom he focused on practical skills and on translating litigation procedure into classroom exercises. Students who took his courses encountered the same attention to process that he applied at the firm. His academic work complemented his practice by sharpening how he explains complex rules to judges, clients, and junior lawyers.
Throughout his career he has maintained professional affiliations and a presence in bar circles in Texas. His background spans clinical representation, big-firm litigation, and legal education. That mix gives him a practical sense of how cases move through systems and how to prepare records for contested proceedings.
He is based in Texas and practices from Locke Lord LLP. His work involves litigation and related legal services arising under Texas law. He continues to split time between client work at the firm and occasional teaching assignments, bringing courtroom experience into the classroom and classroom rigor back to the practice of law.
