Tried and tested over several years as a “line prosecutor,” Anthony Osso has proven himself as a fearless trial lawyer. Raised by two accomplished criminal defense attorneys, the Houston Native was inevitably immersed in the world of criminal law. He now brings his years of courtroom experience and his family’s passion for defending the rights of the accused to the clients of Cogdell Law Firm.   

Before joining Cogdell Law Firm, Anthony served as an Assistant DA for the Harris County District Attorney’s Office, one of the nation’s largest District Attorney’s Offices. As a “line prosecutor” in the Trial Bureau Division, he spent every day in the courtroom, where he worked his way from trying misdemeanors to becoming a Senior Felony Trial Attorney. While in the Felony Trial Bureau, Anthony singlehandedly prosecuted numerous first-degree violent offenders by jury trial, including State of Texas v. Antoine Newton, an abduction and aggravated sexual assault of a child that remained a “cold case” for sixteen years, and State of Texas v. Cruz, a case involving a complex specific intent issue where the Defendant tried to mask the execution of his best friend as an accident. 

After maintaining a nearly perfect trial record, Anthony was recruited to work in the Office’s Domestic Violence Division, where he was responsible for over 40 pending murder cases. In this Division, Anthony served as first chair on numerous first-degree murder trials involving intimate partners, including State of Texas v. Mark Anderson, a bedroom shootout where the Defendant tried to stage the killing as self-defense, and State of Texas v. Luis Romero, a series of murders taking place over several years where the Defendant was ultimately sentenced to life in prison. In addition to his performance in the courtroom, Anthony was responsible for handling the media on several of the Division’s high-profile cases and was often invited to public speaking engagements to provide insight on the topic of Domestic Violence. 

Prior to becoming an Assistant DA, Anthony graduated cum laude from the University of Mississippi, where he double majored in managerial finance and banking management before returning to his hometown to attend South Texas College of Law, where he graduated with high honors. At South Texas, he distinguished himself by competing nationwide in moot court and mock trial competitions and became a National Champion. Anthony was honorarily inducted into The Order of Barristers – an honor society for lawyers who demonstrate exceptional skill in trial advocacy, oral advocacy, and brief writing, and is still asked to return to his alma mater to teach future lawyers about trial advocacy.
