Martha is a sought-out legal and policy advisor on matters where technological advancement, environmental protection, and governance intersect. Her clients are solving today’s major environmental security issues including climate change, PFAS contamination, and ocean plastics. Martha frequently consults on chemical control under the Toxic Substances Control Act (TSCA), as well as initiatives that advance bio-based, sustainable products. Her expertise lies in chemical regulation to help clients open markets and help to keep them open. She is sought-out by clients who need to secure new chemical approvals in a timely way with freedom to operate.

Martha’s experience makes her ideally suited to counsel corporations most likely to experience growth in relation to the Biden-Harris Administration’s initiatives on climate, renewable energy, and national goals to curb plastic waste. These government initiatives will directly result in the need for TSCA support in areas such as electric batteries, bio-based plastics, and products enabled through nanotechnology. A more comprehensive approach to EPA risk evaluations and risk management of existing chemicals under the current Administration makes her experience in negotiating consent orders on chemicals with respect to workplace requirements and downstream processing highly relevant in today’s regulatory environment.
