Cynthia M. Teel

Cynthia Teel advises clients on environmental issues that arise in the litigation, transactional, and regulatory contexts. She has extensive knowledge of state and federal requirements, particularly as they relate to landfills/solid waste, hazardous substances, agriculture, and oil & gas.

Cynthia has represented clients in environmental negotiations/enforcement actions with federal and state agencies and assisted with litigation of environmental claims in administrative, state, and federal courts, including Superfund and odor nuisance class actions. She regularly analyzes real estate deals and tax credit projects for environmental risks and provides strategies for minimizing those risks. Recent regulatory experience includes a focus on emerging contaminants such as PFAS, and dealing with technologically enhanced naturally occurring radioactive materials (TENORM).

Her professional experience prior to law school includes conducting public affairs and media relations for the Los Angeles/Ventura Chapter of the Building Industry Association, and providing public relations services to a variety of organizations ranging from public companies to government entities to not-for-profits.

While at Northwestern, she served as associate editor of the Northwestern University Law Review where she published her student note.
