Environmental Science Associates

Environmental Science Associates (ESA) is a 100% employee-owned environmental consulting firm. We plan, design, permit, mitigate, and restore—for projects across our communities, infrastructure systems, open spaces, and wildlands. We are 50 years strong across 21 offices in California, the Pacific Northwest, and the Southeastern United States.

ESA’s culture is built on mutual respect, recognizing that the collective sum of our individual differences and life experiences fosters our continued success and achievement, for our employee-owners and our clients. We celebrate the differences—age, color, physical ability, ethnicity, family or marital status, gender identity or expression, orientation, language, national origin, race, religion, veteran status, and other characteristics—that make each of us unique. We strive to integrate diversity, equity, and inclusion into all aspects of our project work and the firm’s strategic growth and planning.

Joining ESA means becoming part of a close-knit team of environmental professionals who value learning, creativity, fun, and having the satisfaction of knowing that you have contributed to outstanding projects, improved environmental stewardship, and advanced a more sustainable and resilient future for our communities and wild places.



At ESA, you are an owner, given an equity stake in the firm with the potential to grow every year. You share in the success of the firm because you are responsible for owning and managing your piece of it.
