Mark tries cases and specializes in matters that are preparing for trial. He handles bet-the-company investigations and litigation, but some of his most significant successes have come in cases where he has been able to shut down a prosecution before it becomes public. In over 20 years as a criminal defense attorney, Mark has handled a wide array of matters across the United States and around the world, including representation of individuals in some of the largest fraud cases in history, as well as a range of traditional criminal cases.

Mark’s practice encompasses all manner of enforcement matters, and he has significant experience before a myriad of federal regulatory agencies including the SEC, CFTC, and CFPB. He also regularly deals with formal actions and investigations by the inspectors general from the DOJ, FBI, HHS, IRS, and USDA, to name a few.

In addition to advising companies and boards of directors, Mark maintains a significant number of individual representations, ranging from C-Suite to senior management, in a variety of criminal, civil, and administrative matters. He has extensive experience in Foreign Corrupt Practice Act matters, having represented individuals in some of the largest FCPA investigations in DOJ history.

Mark’s representative experience list is familiar to many, as his clients often attract significant media attention due to the nature of the matter and/or the client itself. His ability to manage public relations comes from years of high-profile representations taken from the headlines. A regular print and broadcast commentator, Mark has been interviewed by numerous media outlets including The Washington Post, The New York Times, Associated Press, CNN, Fox News, NBC, and other local affiliates. 

In one of the most competitive legal markets in the country, Mark has been recognized as one of the Washington Magazine’s Top 100 Lawyers, and consistently ranks as a Super Lawyers Honoree in the area of White Collar Criminal Defense. 
 
In addition to his proven track record as a trial lawyer, Mark is in his twelfth year as an adjunct professor at The George Washington University School of Law. He previously served as an elected member of the Board of Directors for the National Association of Criminal Defense Lawyers, where he is a member of the White Collar Crime Committee, the Sentencing Committee, and has been appointed as the NACDL representative to the American Bar Association 12-member Committee on Standards and Policy.
