Environmental law is among the most fascinating topics facing mankind. It is about how we balance our need to use resources today with the long-term health of our species and our planet. For me, it also marries several interests - scientific interests in geology and chemistry, which I studied in college, and law and economics, which is at the heart of much of environmental law. Today, my practice encompasses a broad range of legal, scientific and technical issues, including contamination of air, soil and water, greenhouse gas emissions and brownfields.

Thomas D. Trapp

Job Titles:
  • Founding Partner
Thomas D. Trapp was a founding partner of Barg Coffin Lewis & Trapp, LLP who passed away in 2007. His insights, intelligence, and equanimity were a foundation of our firm, and he is greatly missed. In Tom's memory, the firm has established the Thomas Trapp Environmental Scholarship at Hastings College of the Law, his alma mater, to honor Tom's legacy in the environmental law community and perpetuate his memory with students entering this field of study. Contributions to the scholarship fund can be sent to: Thomas Trapp Environmental Scholarship Fund, Hastings Alumni Center, 200 McAllister Street, San Francisco, CA 94102, Attention: Gertrude Arnold, Ph.D. Barg Coffin was founded in 2000 by a group of partners who had worked together for many years in the Environmental Law Department of Landels, Ripley & Diamond, a large firm with a long, prestigious history in the San Francisco Bay Area. At Landels, they worked on some of the largest and most influential environmental law disputes of the late 20th century, from the earliest Central Valley pesticide cases in the 1970s, to the first Silicon Valley chlorinated solvent cases in the 1980s, to mass toxic tort/product liability cases and military base cleanup cases in the 1990s. When Landels disbanded in 2000, the Barg Coffin partners established a boutique law firm specializing exclusively in environmental law. Retaining their big-firm expertise and best practices, but in a smaller, more nimble and responsive structure, the new firm of Barg Coffin Lewis & Trapp, LLP, quickly expanded its core client base to include a wide range of businesses, from Fortune 100 corporations to local companies. In 2007, founding partner Tom Trapp passed away unexpectedly at the age of 55. His sharp wit, kindness, brilliance, and legal expertise are still missed by all who were fortunate to have worked with him. Today Barg Coffin has an unsurpassed and award-winning reputation for excellence and expertise in environmental law.
