Ellen D. Marcus is a civil trial lawyer with a proven track record of bringing complex cases to successful and cost-effective resolution for clients, often in matters where they face better-funded adversaries, and often in Virginia federal and state courts. The types of cases Ellen handles include trade secrets disputes, allegations of contract interference, minority shareholder suits, business management and director litigation with breach of fiduciary duty claims, CEOs and CFOs disputing the amount of severance paid them or being sued for breach of non-compete agreements, and lawyers defending against disciplinary charges and malpractice claims.
After 14 years of practicing law in Washington, D.C., where she learned from some of the country’s top trial lawyers and represented plaintiffs and defendants in courts throughout the United States, Ellen crossed the river to Alexandria in pursuit of her dream to have a Virginia-based firm catering to businesses and business people needing expert help in solving their business problems, both in and out of court.
Before co-founding Holmes Costin & Marcus PLLC, Ellen was for seven years a partner at Zuckerman Spaeder LLP in Washington, D.C. Before that, she was an associate at Zuckerman Spaeder, and an associate at Debevoise & Plimpton in Washington, D.C. Ellen began her legal career as a law clerk for Judge Leonie M. Brinkema of the U.S. District Court for the Eastern District of Virginia.
Ellen received her law degree from the Columbia School of Law, where she was a senior editor for the Columbia Law Review and a Harlan Fiske Stone Scholar. She received her bachelor’s degree in political science, magna cum laude, from Amherst College.
