Career

Kellie Lerner is a nationally recognized antitrust lawyer who is regularly sought out by individuals and businesses to solve their most complicated antitrust problems. For nearly 25 years, Kellie has primarily devoted her practice to all facets of competition law. She is a leading voice on antitrust issues and has served at the highest levels of leadership in national professional and advocacy associations dedicated to the field of competition law.

Chambers USA recommends Kellie as “a brilliant tactician and a fierce litigator.” A teambuilder by nature, she has been praised as someone “who mixes vision and skill with respect” and who can “get large teams of people to work effectively together.” Kellie’s inclusive leadership has yielded historic results in a variety of industries, with notable depth of experience in health care, where she has successfully tackled unlawful price fixing, market allocation and monopolization violations.

Kellie is particularly adept at identifying new antitrust actions, initiating antitrust class action lawsuits that have ultimately held antitrust violators accountable for billions of dollars in settlements. Chambers USA hails her as a “trendsetter in taking on difficult and innovative cases” and Legal 500 commends her “superior intellect, determination and political savvy in getting the job done.”

Kellie also advises companies in a variety of industries, including technology, alternative energy and entertainment, on pressing antitrust issues that involve regulation, compliance and affirmative litigation.
