About
Louis E. Grube is a partner at Flowers & Grube, where his practice centers on appellate litigation. He joined the firm in 2018 after working for the Supreme Court of Ohio and became a partner in 2022. He handles civil, criminal defense law, and administrative appeals at multiple levels of Ohio’s judicial system. He has helped develop the firm’s criminal appeals practice and represents individuals seeking review of convictions and other court decisions. His appellate work requires detailed legal research, written advocacy, oral argument, and careful analysis of trial records and procedural issues.
Louis earned his Bachelor’s Degree from Oberlin College and his J.D., with honors, from Suffolk University Law School. His official firm biography identifies him as a 2008 Oberlin College graduate and a 2013 honors graduate of Suffolk University Law School. After law school, he entered private practice before beginning a four-year clerkship with Justice William M. O’Neill of the Supreme Court of Ohio. That experience provided extensive exposure to appellate procedure, judicial decision-making, legal briefing, and complex questions arising before the state’s highest court.
Louis returned to private practice when he joined Flowers & Grube. His experience prepares him to handle appeals involving civil litigation, criminal matters, and administrative proceedings. He is admitted to practice before the Supreme Court of the United States, US Courts of Appeals for the Sixth and Fourth Circuits, US District Courts for the Northern and Southern Districts of Ohio, and state courts in Ohio and Colorado. His official biography also identifies him as an Ohio State Bar Association Certified Appellate Law Specialist and certified for court-appointed capital appeals in Ohio.
Louis E. Grube has a broader appellate practice that involves examining records from earlier proceedings, identifying preserved and potentially reversible legal errors, preparing appellate briefs, and presenting arguments before reviewing courts. His background at the Supreme Court of Ohio and subsequent appellate practice give him experience with cases moving through both state and federal court systems, while his work at his law practice remains focused on representing clients during complex post-trial and appellate proceedings.
