Genus Heidary focuses much of her practice on environmental, health, and safety-related matters, providing both proactive compliance counseling, as well as strategic advocacy at times of enforcement litigation. She has comprehensive experience counseling clients through major industrial accidents, workplace fatalities, agency inspections, and crisis management at times of potential toxic releases. Genus works with technical experts and auditors, providing compliance counseling in relation to the development and improvement of environmental, health, and safety programs. Much of this work requires her to take the lead on internal investigations to evaluate litigation risk, as well as compliance readiness. Her portfolio also includes due diligence risk assessments of commercial deal work.

With a background in public policy and years of courtroom experience as a litigator, Genus also represents clients from a broad array of industries - including manufacturing, health care, technology, energy, real estate, and financial services - in challenges to agency rule-makings, supervisory investigations, complex litigation, and class action lawsuits, as well as civil and criminal enforcement actions brought by federal and state regulatory agencies, state attorneys general, and the Department of Justice (DOJ).  Such experience has allowed her to represent clients before agencies including the Department of Labor (DOL), Environmental Protection Agency (EPA), Consumer Financial Protection Bureau (CFPB), Office of the Comptroller of the Currency (OCC), Federal Trade Commission (FTC), and the Federal Reserve Board, or related state agencies.

Prior to becoming an attorney, Genus worked in healthcare management and health policy capacities.
