About Mary Kathryn
Mary Kathryn Brown began her legal path in central Texas classrooms. She completed a Bachelor of Arts in political science at Concordia University-Texas in 2015 and earned her Juris Doctor from St. Mary’s University School of Law in 2019. Her time in law school included roles that bridged academic work and courtroom exposure.
While a student, Brown worked as a law clerk in the Hays County Criminal District Lawyer’s Office in 2017. That position put her into the day-to-day work of a trial office and exposed her to criminal dockets and courtroom procedure. In 2018 she served as a teaching assistant at St. Mary’s, supporting classroom instruction and helping students navigate substantive coursework. The same year she gained appellate experience as a legal intern at the Texas Third Court of Appeals, observing opinion drafting and appellate argument preparation.
After completing law school, Brown joined Walters Gilbreath, PLLC as an associate lawyer in 2019. She entered private practice at a time when courts and clients were adapting to new challenges. Her early professional years combined courtroom experience from the clerkship with insight into appellate practice from the court internship, giving her a practical grounding across levels of the Texas justice system.
Colleagues describe Brown as methodical in her preparation. She approaches filings and hearings with an eye for procedure and a preference for concise, direct legal writing. Those habits were visible during her tenure in both the criminal district office and at the appellate court, where attention to record and precedent is critical.
Brown’s progression from law student to associate was steady and chronological. She moved from academic support roles to hands-on public service in a county prosecutor’s office, then to appellate observation, and finally into private practice. That trajectory reflects an interest in understanding multiple stages of litigation rather than a narrow subspecialty.
She is licensed to practice in Texas and is based at Walters Gilbreath, PLLC. In her current role she works on matters that arise in Texas courts and continues to build her practice at the firm.
