Jonathon Muñoz, Texas appeals attorney in Mission, Texas

Jonathon Muñoz is a Texas lawyer who handles appeals, post-conviction writs, and mandamus for people across the state. He runs Law Nerd LLC from Mission, in the Rio Grande Valley, and works in English and Spanish.

Before opening the firm in 2025, he was a staff attorney at the Thirteenth Court of Appeals of Texas from 2023 to 2025. In that role he researched cases and drafted proposed opinions for the justices in civil and criminal appeals. Before that, he clerked for U.S. Magistrate Judge Scott J. Hacker in the Southern District of Texas, prosecuted cases as an assistant district attorney in Hidalgo County, and practiced criminal defense, criminal appeals, and post-conviction law in Iowa.

That background covers the defense side, the prosecution side, and the court's side of a case. He charges flat fees for appellate work so clients know the full cost before they hire him.
