Mark’s practice centers on litigation, where his clients have scored wins over billion-dollar multimedia conglomerates, Fortune 500 companies, and all manner of professional detractors. Clients describe Mark’s arguments as “inspired” and “works of art,” and judges at every level of the federal judiciary—including the U.S. Supreme Court—cite his writing as authority in major cases. Mark has been instrumental in obtaining corrections and retractions from print publications, television broadcasters, and movie studios, but many of his most important wins come from nipping false and defamatory narratives in the bud, before they ever imperil his clients’ reputations. Mark’s discernment and knack for making complicated points intelligible help his clients to consistently make their best cases—not just in court, but to publishers and the public.
Before building his practice as a defamation and First Amendment lawyer, Mark was a deputy director at a federal agency, an appellate and administrative lawyer at an AmLaw 100 firm, a law clerk for three federal judges, a team member at a wind energy developer, and a speech writer, policy analyst, and media director for a Wisconsin senator. Besides defamation and First Amendment law, Mark has substantial experience litigating and counseling clients on matters involving intellectual property and administrative law.
