Ryan Patrick, a former U.S. attorney in the Southern District of Texas, has joined Haynes and Boone as a partner in Houston in the white-collar and government investigations practice.

Patrick, who resigned as U.S. attorney in Houston as of Feb. 28, started work Monday at Haynes and Boone, after taking three weeks off to spend time with his wife and four children. A former assistant district attorney in Harris County, and state district judge in Houston, Patrick had served as U.S. attorney in the busy federal district covering a wide swath of Southeast Texas since 2018.
