About Mark R.
Mark R. Dunn graduated from the University of Minnesota Law School in 1991. He entered the legal profession at a time of change in the early 1990s and has since built a practice that crosses state and federal lines. He keeps a steady, methodical approach to cases and to the business side of law. Colleagues describe him as practical and direct.
Dunn is admitted to practice in Missouri and Texas. He also holds admission to practice before the U.S. Court of Appeals for the Fifth Circuit and the U.S. Supreme Court. Those admissions give him the ability to handle matters that move between state trial courts, federal appellate courts, and, in rare cases, the nation’s high court.
His career includes work at Osburn, Hine & Yates LLC, where he serves as an attorney in the firm’s offices. At the firm he has been involved in matters that require coordination across multiple jurisdictions. He has represented clients in hearings and filings that touch state and federal rules, and he works with the firm’s team on case strategy, motion practice, and preparation for trials and appeals.
Dunn maintains active memberships in the Missouri State Bar and the Texas State Bar. Those memberships reflect his practical ties to both state legal communities. He participates in bar activities and stays current on continuing legal education requirements that govern practice in those states.
Throughout his work he handles litigation and appellate matters that arise in the jurisdictions where he is admitted. He has experience preparing briefs, drafting pleadings, and presenting legal arguments to judges and panels. His practice requires attention to procedural detail as well as to the facts that underpin client claims and defenses.
He brings a courtroom-ready mindset to cases that may travel beyond a single state line. Clients and opposing counsel see him as steady and prepared. He currently practices at Osburn, Hine & Yates LLC, where his work centers on litigation in state and federal courts.
