Noah maintains a national environmental and energy practice involving complex litigation, regulatory counsel, and transactional matters.

“My goal, at every juncture, is achieving client success. Whether preparing for a jury trial, assisting a client with a confidential or sensitive legal matter, or handling a critical development project or major deal, every strategic decision I make is not only based on a complete understanding of the relevant legal framework and the key points of persuasion but fundamentally, the relationship of the strategy to a final successful outcome for the client.”

He has significant litigation experience and has tried jury and bench trials. At the same time, Noah regularly helps clients devise solutions to difficult regulatory problems, represents clients in connection with administrative proceedings and enforcement matters, assists clients with deals and development projects, and represents clients in connection with energy-related transactions.
