What is Lawdragon?

Lawdragon is one of the country’s most trusted and popular legal media companies. It reports on important legal news stories and legislative updates. Lawdragon also reviews and appraises attorneys that it believes to be at the top of their practices, who are then curated in its annual 500 Leading Plaintiff Consumer Lawyers list. Peer nominations are used to begin this process, which helps keep it open to any practicing attorney.

In its 2022 edition announcement, Lawdragon said this about the attorneys who made the list: “From the opioid epidemic to toxic substances and defective products, truck accidents to wildfires and sexual abuse, these are the lawyers who stand on the front line in individual lawsuits and class actions seeking justice. They relish their role of underdog, taking on the toughest cases and typically only getting paid if they win. Talk about heroes.”
