For a law firm whose first clients personally shoveled their wealth out of the ground, it’s perhaps not surprising that 97-year-old Davis Graham & Stubbs still specializes in natural resources and energy. But the Denver-based corporate firm is adding clients in financial services, health care and technology.

“As you’d expect, being from Denver, a lot of our work is still based in natural resources, but we’ve grown with the region,” said managing partner Christopher Richardson, who joined the firm out of law school in 1983. “Our strength has always been having people with deep industry knowledge who can be partners to our clients — to help take them to the next level.”
