The effective practice of environmental law demands more than knowledge of the maze of local, state and federal regulation and legislation. It requires the ability to identify regulatory opportunities, assess the regulatory and political climate, gauge community attitudes, and counsel businesses on how to operate profitably within the boundaries of the law.

The Firm’s environmental lawyers represent clients in transactions, regulatory proceedings, and litigation involving federal, state, and local environmental laws. Our clients include multi-national corporations, industry associations, independent developers, public  companies, ski areas, upstream and midstream oil and gas companies, mining ventures, renewable energy developers, landowners, entrepreneurs, and investors. The Firm advises clients not merely on Colorado matters, but on some of the most sophisticated and cutting-edge environmental issues arising throughout the country.

Our environmental attorneys have been recognized by Best Lawyers in America, Chambers USA (Band 1), Super Lawyers, and other publications.
