Evergreen Engineering, Inc. was incorporated in 1985 with headquarters in Eugene, Oregon. We originally served mainly the forest products industries (wood products and pulp & paper) that used to be predominant in the Pacific Northwest.

In 2016, Evergreen opened an office in Atlanta, Georgia to better serve clients in the southeastern United States.

As early as 1986, Evergreen began to diversify into other industries, including metals (steel and titanium) and chemicals (adhesives). This diversification continued over the next few years into power and energy systems, especially as related to utilities for industrial plants.

Evergreen has always striven to anticipate new technologies and industrial trends, and to be prepared with the tools and expertise to meet these challenges. Evergreen initiated its own research of alternative emission control technologies to be prepared to offer industrial clients the best technical solutions.
