Career

Heather is a partner in Freshfields' antitrust, competition and trade practice, based in Washington, DC who specializes in antitrust litigation, and has spent the last 20+ years helping her clients successfully navigate complex antitrust matters pending in state and federal courts, as well as enforcement actions before the US Department of Justice (DOJ), the Federal Trade Commission (FTC), and state attorneys general.

Heather prides herself in being a creative litigator with a long history of getting antitrust cases dismissed at early stages for her clients, defeating class certification in a large multi-district litigation case, as well as trying antitrust cases before both judges and juries. Her experience spans a wide variety of claims – from conspiracy claims of market allocation or price-fixing, to monopolization claims of exclusive dealing, bundling, tying to and unfair competition claims.

In addition to litigation, Heather defends companies and individuals in criminal price-fixing (cartel) investigations before the DOJ and worldwide regulators, including being involved most of the large, global cartel investigations over the past two decades.
