Antonia Stamenova-Dancheva counsels clients on consumer protection and regulatory matters, including compliance with federal and state requirements governing product safety, advertising and promotion, and environmental claims. She represents clients before state and federal agencies, including the Consumer Product Safety Commission (CPSC), Federal Trade Commission (FTC), state Attorneys General, and state regulatory agencies. She also assists clients in advertising disputes before the National Advertising Division (NAD).

Prior to joining Keller and Heckman, Antonia served as product safety and compliance counsel at a major online marketplace, where she supported strategic initiatives while working with business, product assurance, regulatory, and technical teams to proactively manage risk. She also represented the company in negotiations with the CPSC and coordinated responses to outreach from state Attorneys General, federal regulators, and federal legislators. Before that, Antonia spent more than a decade in the Los Angeles and Washington, DC offices of a large New York-based law firm where she represented companies in consumer class actions and settlement negotiations.

Antonia leverages her combined litigation, in-house counsel, and current regulatory experience to provide holistic advice to meet her clients’ complex needs and, if necessary, guide them through civil investigations, enforcement matters, and litigation. She counsels clients on product safety and compliance issues across a wide range of consumer products, including toys, infant and children’s products, apparel and textiles, personal care, home goods, furniture and furnishings, luggage, electronics, and tech accessories. Antonia assists clients in evaluating legal requirements; assessing potential product hazards; preparing reports to regulators; negotiating and managing recalls; and developing compliance programs to meet legal obligations, enhance product quality and safety, and manage legal exposure. Antonia also advises clients on marketing and advertising dos and don’ts, testing, labeling and warnings, and claim substantiation and qualifications. 

Antonia is a frequent contributor to Keller and Heckman’s Consumer Protection Connection blog and other publications, and a sought-after speaker. Antonia’s recent article, Passing the Buck on Recycling: Textiles as a Case Study of State EPR Laws, co-authored with Keller and Heckman Partner Sheila Millar, was published by the Washington Legal Foundation.
