Ryan Patrick

Ryan Patrick is a partner in Haynes Boone’s Houston office in the White Collar and Government Investigations Practice. Ryan is an experienced investigator and trial lawyer who has handled or supervised nearly every type of criminal and civil enforcement matter. It doesn’t matter if the investigation originates with the Department of Justice, the state Attorney General or local law enforcement. Ryan has seen it all.

Ryan’s experience comes from years in the courtroom, first as a state prosecutor and then as a Texas district court judge. In 2017, Ryan was nominated and unanimously confirmed as United States Attorney for the Southern District of Texas, serving from 2018 to 2021. Ryan oversaw one of the largest DOJ offices and the busiest criminal docket in the country. During his time as U.S. Attorney, prosecutors in his office charged nearly 25,000 defendants in almost 22,000 cases, consistently ranking as the top district nationally in overall criminal prosecutions and criminal appeals.

Ryan has handled a broad array of white-collar cases as a state and federal prosecutor, including False Claims Act, Foreign Corrupt Practices Act (FCPA), and money laundering investigations involving foreign actors, public officials and corporate defendants in the banking, biotech, energy, healthcare and space industries. During Ryan’s time at the district attorney’s he was a specially trained investigator and prosecutor in the vehicular crimes section and he finished his career with the district attorney’s office assigned to the Special Crimes/Major Offenders section. There the most complex and dangerous criminal organizations were investigated and taken to trial. One of Ryan’s final trials was the successful prosecution of a 1982 cold case murder concluding with a life sentence.

Ryan also maintains a criminal state court practice. Not only does Ryan continue to represent individuals accused of crimes in Texas state courts, but also works with the Houston Volunteer Lawyer’s Association assisting individuals attempting to seal or expunge old criminal records as they work on moving past old mistakes. State court cases are often more reactionary and unlike most federal investigations, the target in a state case often doesn’t know what’s about to happen.

Ryan’s extensive experience in the courtroom is evidenced in more than 60 first and solo chair jury trials and has presented oral arguments before the 5th Circuit Court of Appeals. As a judge Ryan presided over more than 100 jury trials in four and a half years on the bench.

Having earned his private pilot’s license in 2007, Ryan’s knowledge and passion in aviation has additionally helped him advise clients involved in FAA investigations. Additionally, having been a state elected official, Ryan’s knowledge of the Texas Ethics Code has benefited clients navigating state campaign finance laws.
