As a partner in our Environment and Natural Resources practice area, Tom has deep ties to both the energy and government sectors in California and across the west. He has extensive experience assisting clients with the navigation of California environmental regulations including responding to information requests, Cleanup and Abatement Orders, and Cease and Desist Orders issued by the Regional Water Quality Control Boards and resolving enforcement actions brought by California regulatory agencies.
