Ryan Patrick

Ryan Patrick is a partner in Haynes Boone’s White Collar and Government Investigations Practice. Ryan is an experienced investigator, judge and trial lawyer who has handled or supervised nearly every type of criminal and civil enforcement matter. There are few lawyers with Ryan’s unique experience.

Ryan has spent his career in the courtroom, first as a state prosecutor, then as a Texas district court judge, and finally as the United States Attorney for the Southern District of Texas. From 2018 to 2021 Ryan oversaw one of the largest DOJ offices and the busiest criminal and appellate docket in the country.

Ryan has handled a broad array of white-collar and traditional criminal cases in federal and state courts, including the False Claims Act, Foreign Corrupt Practices Act, and money laundering. He has both investigated and represented foreign actors, elected officials and corporate defendants in the banking, biotech, energy, healthcare, and space industries. During his time as an assistant district attorney, Ryan was a specially trained prosecutor in the investigation of vehicular fatalities, and he finished his state career assigned to the Special Crimes/Major Offenders section where he handled proactive investigations into the most complex and dangerous criminal organizations along with other one-off exceptional cases. Two of his final trials as state prosecutor were securing a life sentence in a 30-year-old cold case murder and the successful prosecution of a man who spray painted a locally displayed Picasso.

Along with a robust federal defense practice, Ryan still maintains a criminal state practice representing individuals and companies under investigation or charged under Texas criminal statutes. Ryan is the first call from his partners at Haynes Boone for state criminal matters – from corporations facing state Attorney General civil investigations to individual clients under arrest or investigation for any type of state crime.
