Sean C. Grimsley
Sean Grimsley serves as trial counsel and legal advisor in high-profile litigation matters, both in the U.S. and abroad. Sean has a diverse practice, including antitrust, oil and gas, class actions, accounting malpractice, and intellectual property matters. Most recently, he first-chaired a $50-million damages trial for client Tyco where he and his team stepped in months before trial and obtained a jury verdict for roughly 10% of plaintiffs’ demand, which a previous jury had awarded in full. In the last four years, Sean and his colleagues have tried a multi-billion dollar antitrust jury case in Texas state court (which settled favorably during trial), won a major class action appeal in the Seventh Circuit, and tried a patent case and separate post-verdict damages proceeding in the Eastern District of Texas. Sean has also served as lead counsel and advisor for a major U.S. oil company in both China and the U.S. regarding a highly-publicized oil spill in Chinese territorial waters.
Sean recently served as Deputy Chief Counsel to the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling in Washington D.C. Sean and Fred Bartlit investigated and presented findings to the President's Commission regarding the root causes of the worst oil spill in the nation's history. You can see Sean at the two-day hearing where the investigative team presented their findings here: http://www.c-spanvideo.org/seangrimsley. The Chief Counsel's report is available here: http://www.eoearth.org/files/164401_164500/164423/full.pdf. The Co-Chairs of the Commission, Senator Bob Graham and Bill Reilly, describe the investigative team’s work here: http://www.bartlit-beck.com/about-news-155.html.
Sean has tried eleven cases, argued three appeals, and advised on and prepared to try many others. Sean’s breadth of experience representing both defendants and plaintiffs ensures that early case assessment, discovery, motions practice, and expert work focus on the facts and arguments that actually matter to achieving the best possible result at trial or through settlement.
Prior to joining the firm in 2004, Sean served as law clerk to Justice Sandra Day O’Connor of the U.S. Supreme Court and Chief Judge Harry T. Edwards of the U.S. Court of Appeals for the D.C. Circuit. Sean also worked for two years as an Assistant Federal Public Defender in Washington, D.C. serving as trial and appellate counsel for indigent criminal defendants in federal court. Sean graduated summa cum laude from Michigan Law School in 2000. He obtained a B.A. in Plan II Honors and Biology with Highest Honors from the University of Texas in 1994. He lives in Denver with his wife Emily and their three wonderful (most of the time) children.
