Aaron M. Diaz started his criminal defense career at the age of 17, spending six years as a legal assistant for a criminal defense firm in Edinburg, Texas. In February 2018, over a decade later, Aaron began clerking for Cynthia E. Orr and Gerald H. Goldstein. As a clerk, Aaron worked on complex criminal matters including capital murder, drug trafficking, sexual assault, and fraud cases. Aaron also worked diligently on state and federal writs of habeas corpus and appeals, and assisted in preparing for oral arguments before the Fifth Circuit Court of Appeals in New Orleans on a health care fraud case.
Aaron has extensive experience working in the legal field. Prior to clerking with Goldstein & Orr, he spent several years working as a paralegal for various Texas government agencies including the Office of the Solicitor General. As a paralegal for Texas’s chief appellate attorney, Aaron developed a strong passion for appellate practice by working on complex, high profile cases. Aaron also worked for the Hays County District Attorney’s Office, where he handled open records and appeals.
Before graduating from St. Mary’s University School of Law, cum laude, Aaron received his Bachelor of Science in criminal justice from the University of Texas–RGV (formerly UT-Pan American) in his hometown of Edinburg, Texas. He later received a Master of Arts in legal studies from Texas State University in San Marcos, Texas.

During his first year, Aaron received the Excellence in Writing Award or “Super Brief,” which is awarded to a first-year law student who demonstrates superior brief writing skills. Additionally, Aaron represented St. Mary’s Law in The Paper Chase legal writing competition, where he placed third in the state. Aaron was also a staff writer and senior associate editor for the St. Mary’s Law Journal. His student comment entitled, Restoring the Presumption of Innocence: Protecting a Defendant’s Right to a Fair Trial by Closing the Door on 404(b) Evidence, was published in Volume 51 of the St. Mary’s Law Journal.
During his third year of law school, Aaron served as a student defense attorney in the St. Mary’s Criminal Justice Clinic where he represented poor and disenfranchised persons in various criminal courts pro bono. Aaron’s service to the Clinic earned him the Francisco Leos Award for Excellence in Clinical Studies.
