Lauren Aronson is an Advertising & Media partner in Crowell & Moring’s Washington, D.C. office. Lauren represents clients across a variety of industries in advertising and marketing law. She has assisted numerous clients in initiating and defending false advertising challenges before the National Advertising Division (NAD) of the Council of Better Business Bureaus (CBBB), and the National Advertising Review Board (NARB), and has provided counsel in Lanham Act false advertising suits. Lauren has also represented clients in investigations and actions brought by the Federal Trade Commission and state attorneys general relating to marketing and sales practices.

In addition to handling litigation-related matters, Lauren advises clients regarding the development, substantiation, approval, and defense of advertising claims. When additional support is necessary to support desired claims, Lauren works with her clients to develop the needed substantiation. She counsels clients on a range of advertising-related issues, including social media, native advertising, telemarketing, rebates, warranties, right of privacy and publicity, and endorsements. Lauren has also worked with clients to develop and enforce Minimum Advertised Price (MAP) policies; draft and amend privacy policies and terms of use for websites and mobile applications; and has advised on compliance with telemarketing laws, state dairy marketing laws and regulations, and other advertising and marketing-related concerns.
