Jamie Jefferson is a partner with Barg Coffin Lewis & Trapp, LLP.

Jamie brings extensive experience litigating under CERCLA, RCRA, the California Hazardous Waste Control Law, CEQA, NEPA, and Prop 65 to the firm. Prior to joining the firm, Jamie worked as a Deputy Attorney General in the environment section of the California Department of Justice for 19 years. In that role, Jamie represented state agencies in enforcement actions and defended state agencies, including DTSC, OEHHA, and CARB.  Most recently, Jamie led multi-state litigation for the State of California challenging federal agency actions arising under NEPA, the ESA, EPCA, and the APA.

Prior to working for the State, Jamie co-founded an environmental law firm focusing on representing citizens groups in environmental litigation against the federal government. Jamie began her career at an Oakland law firm representing real estate clients. 

I grew up in urban Los Angeles, but was always drawn to natural spaces such as the nearby Santa Monica mountains and the Pacific Ocean. Originally, I focused my career in environmental law out of a desire to protect cherished natural spaces and safeguard the planet. While I have litigated for almost twenty years, as my career has evolved, I have developed more interest in helping clients make wise use of natural resources, develop sustainable practices, and comply with a rapidly changing regulatory environment. Environmental law is fascinating because being effective requires continual learning as the regulatory and legal environment evolves to keep pace with scientific and technical breakthroughs.
