Her practice focuses on helping clients navigate situations where regulatory exposure, operational demands, and public scrutiny converge. She advises on complex civil and administrative litigation, enforcement defense, and compliance strategy under federal and state environmental laws, including the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and Resource Conservation and Recovery Act (RCRA). Leigh is particularly experienced in matters involving parallel proceedings across agencies and courts, where success depends on aligning legal, technical, and business considerations.

Leigh has developed a deep practice in the solid waste and heavy industry sectors, where she regularly advises on high-risk operational and regulatory challenges. She plays a central role on a large, high-profile landfill matter involving a complex subsurface reaction that has led to significant regulatory oversight, enforcement activity, and civil litigation. In that context, she coordinates legal and technical teams, shapes compliance and enforcement strategy, and guides clients through fast-moving, high-visibility issues. Her experience in this space gives her a practical understanding of landfill operations and the regulatory frameworks that govern them, allowing her to provide advice that is both legally sound and operationally grounded.

Her litigation experience includes defending nuisance and mass tort claims, developing and executing expert-driven case strategies, and leading key components of dispositive and appellate efforts in complex, multi-forum disputes. She has also played a central role in high-exposure matters involving injunctive relief and post-trial proceedings, coordinating factual, technical, and legal strategies to advance cohesive, effective defenses.

In the contaminated sites arena, Leigh has played a key role in major Superfund allocation proceedings and advises clients on natural resource damage and remediation-related liabilities.
