Court VanTassell’s practice focuses on environmental regulation and energy litigation.  Court represents clients ranging from global energy corporations to start-up companies and he advises on all aspects of the use and management of natural resources, including environmental compliance, conservation, remediation, and litigation. 

Court has particular experience advising oil and gas operators in matters related to upstream environmental compliance and the management or restoration of oilfield properties.  He also frequently handles matters concerning wetlands, coastal land loss, NORM, waste disposal, and industrial facility permitting. 

Prior to his law practice, Court was a field biologist for an environmental non-profit and he managed an endangered species program for the U.S. National Park Service.  With his science background and years of government experience, Court provides clients with a diverse and efficient approach to environmental issues. “I believe a broad combination of scientific, governmental, and legal experience provides a unique toolset for tackling complex environmental issues and working in tandem with experts and agencies to efficiently achieve a client’s goals.”

After Hours

Court enjoys spending time outdoors, particularly hunting, kayaking, and camping with friends and family. He grew up in northern California and, when possible, still enjoys skiing, scuba diving, or returning to Napa to catch up on the latest vintage. He and his wife are still avid travelers, but their favorite destination is their backyard to play outside with their three young sons.
