We have worked alongside stakeholders in the energy and resources industries since the inception of our firm 70 years ago.

As the industry has changed and expanded to include everything from oil and gas and mining to alternative energy and renewable sources, our professionals have kept pace. We partner with our clients to develop strategies that will sustain their operations through the cyclical market forces that impact this dynamic industry, from the price of oil or gold, to the global economy, to domestic air, water, and safety regulations.

We help established companies and new industry entrants alike to evaluate and capitalize on new opportunities and efficiently mitigate the impacts of challenges they face along the way. We proudly serve eight of the ten largest oil and gas companies operating in the United States as well as several of the nation’s leading traditional and renewable power generators and developers. From vanadium to precious metals, uranium, and coal, our deep knowledge of the mining industry is rooted in the groundwork laid by Joe Holland and his College of Mines colleagues.

With offices in states with some of the most productive resources in the U.S. - Montana, Nevada, New Mexico, and Wyoming - we have the local connections and relationships to help clients acquire, sell, or develop many of the most significant energy assets in the nation.
