Tim Simeone is co-chair of HWG LLP’s Issues & Appeals and Legal Ethics & Malpractice groups. A trusted advisor across practice areas, Tim also works extensively with the firm’s Telecommunications and Litigation & Investigations practices.
Among the small group of attorneys who represent lawyers before the D.C. Office of Disciplinary Counsel (ODC), Tim’s background is unique: thirty years as a hands-on brief writer and advocate before courts, government agencies, and the ODC itself. Law firm general counsel call on that experience for the high-quality written work and reliable judgment that high-stakes disciplinary proceedings demand.
Tim has represented attorneys from AmLaw 100 firms, prominent D.C. firms and boutiques, and small practices — as well as former political appointees and Department of Justice attorneys — in matters threatening disbarment and other severe sanctions. Resolving an ODC inquiry before it proceeds to a hearing and becomes public is critical, and Tim’s record of doing exactly that is exceptional. When matters do proceed to a hearing, Tim is prepared to lead complex matters through that process and, if necessary, through appeals. Tim has successfully argued multiple disciplinary appeals before the D.C. Board on Professional Responsibility and the D.C. Court of Appeals.
Tim’s appellate experience includes lead drafting on scores of briefs in federal and state courts of appeal, and he remains as committed to his writing as he is to oral advocacy. He has argued before the United States Supreme Court, the D.C. Circuit, other federal courts of appeal, and state courts of last resort. His focus on distilling complicated issues into plain English carries into his advocacy before the Federal Communications Commission and its Office of General Counsel. In his practice with HWG’s Litigation & Investigations group, Tim has also briefed and argued motions before the district courts and the U.S. Court of Claims, provided clear mediation statements in complex commercial matters, and worked on internal investigations in the United States and abroad.
Before entering private practice, Tim clerked for Judge Patricia Wald of the D.C. Circuit and Justice David Souter of the United States Supreme Court. Tim also served as a visiting professor at Villanova University’s School of Law and has published and lectured extensively on topics including legal ethics, constitutional law, trial and appellate litigation issues, and administrative law.
