John offers clients the benefit of decades of experience as a top environmental lawyer, a leader of major bar and environmental organizations, and a distinguished military career.

John provides strategic counsel on high-stakes environmental and natural resources litigation, civil and criminal enforcement, and compliance. Working with clients makes the practice of law worthy and valuable to him as they advance strategic needs while protecting human health and the environment.

For more than two decades, John served as a senior leader on environment and natural resource matters at the United States Department of Justice (DOJ), where he supervised some of the department’s most significant litigation, including the Exxon Valdez oil spill, Love Canal, and Bunker Hill litigation. As the Senate-confirmed, Assistant Attorney General, ENRD, John worked on the most high-profile environment cases, and personally negotiated the multi-billion dollar resolutions of the Deepwater Horizon oil spill and the Volkswagen emissions scandal. These cases required a great deal of coordination, expert assistance, and sophisticated management of numerous players to reach successful outcomes. This experience has given John insight into the workings of large corporations, as well as into the challenges that major companies face in lawsuits.

As the former President of the Environmental Law Institute, the former Chair of the American Bar Association (ABA) Section on Environment, Energy, and Natural Resources, and the immediate past President of the American College of Environmental Lawyers, John has led each of the premier environmental organizations in the United States. In addition, he was the first government attorney to be elected and serve as the President of the District of Columbia Bar, now the largest bar in the nation.
