Marc represents plaintiffs and defendants in cases involving a wide array of civil claims in both trial and appellate courts. His meticulous attention to detail, knowledge of relevant changes in the law, and ability to craft highly persuasive briefs have led to a particularly strong record of success on appeal.

For example, Marc recently represented a steel distributor at trial and during appeal in a Sherman Act antitrust case against several large steel distributors and manufacturers arising from defendants’ efforts to prevent a new distributor from entering the market. The jury returned a verdict in favor of his client, who received a judgment of more than $160 million after the imposition of treble damages, costs, and attorneys’ fees.

In addition to his antitrust work, Marc has achieved successful outcomes in disputes relating to oil and gas issues, securities fraud, product liability, trade secret misappropriation, construction law, breach of contract, fraudulent transfer, breach of fiduciary duty, defamation, negligence, and wrongful death, among others.

Before joining Schiffer Hicks Johnson, Marc was a partner at Yetter Coleman and, previously, an appellate lawyer at Weil, Gotshal & Manges. Prior to entering private practice, he served as a law clerk to the Honorable Edith H. Jones of the United States Court of Appeals for the Fifth Circuit.
