The Firm’s lawyers accept only a small number of high-stakes cases at any given time so that they can dedicate their full attention to every client. The Firm’s founder, David Oscar Markus, is a Harvard-educated lawyer who has been described as “wickedly smart and a terrific trial lawyer.” His clients say that he is “the whole package” and “a creative, courageous and tenacious courtroom advocate.” One recent publication said: “David Markus is amazing, not only because of the strength and genius of his arguments and motions, but also because of his brilliant and astonishing performances during the hearings. Additionally, he radiates so much confidence, and that in itself soothes the usual anguish and anxiety that you endure during these types of situations. Last but not least, he is such a great human being.”

The Firm handles a wide variety of criminal defense matters, with an emphasis in representing business-people and professionals in federal white-collar investigations, prosecutions, and appeals around the country.  For example, Markus/Moss has successfully represented CEOs in complex criminal antitrust cases and fraud cases, doctors in health care fraud cases, lawyers in mortgage fraud cases, politicians in election fraud investigations, companies and executives in environmental matters, and so on.
