Galloway Environmental, Inc. has been providing environmental services throughout the United States since 1995.

Galloway Environmental, Inc. (GEI) is a Small Business Enterprise that was established in 1995 to provide innovative and sustainable environmental, health & safety, and construction support services.  GEI’s expertise focuses on five distinct service categories, Environmental Due Diligence and Remediation, Industrial Hygiene, Health and Safety, Natural Environment, and Construction.  Although each category is distinct in itself, we often incorporate several of the categories in our projects. By doing so, we are well equipped to provide our clients with a “one-stop shop” experience, thereby reducing redundancy, expediting project schedules, and reducing overall project costs.

Our team has extensive experience working on private and public sector projects throughout Washington, California, Montana, Oregon, Hawaii, and Guam under the multitude of regulations, thus providing us with the unique understanding and skillset to complete our projects with the most progressive and cost effective methods.  However, being locally owned and operated, GEI has a unique understanding of the business and regulatory climate in the Pacific Northwest.
