Forest RoadLEI was founded in 1981 by Dallas C. Hemphill, P.E., ACF. From its inception, LEI was known as Logging Engineering International, Inc. The Eugene-based company quickly became a leader in the Logging Engineering/Forest industry under Mr. Hemphill’s leadership as it gained a reputation for providing unparalleled logging systems and transportation engineering services throughout the west coast and offshore.  
Through the late 1980s and 1990s, LEI continued to grow in reputation and size, undertaking large scale logging systems and transportation planning and field verification projects in extremes of isolation, climate, terrain, timber types and culture. Fielding teams as large as 25 professionals, LEI established a solid track record throughout the Pacific Northwest, from the Southern tip of South America to Siberia and Alaska and along the rugged terrain of many tropical and temperate locations.
In the early 2000s, LEI began diversifying its professional services by adding a licensed Land Surveyor to its team of professionals. As with its track record in the Forest Industry, LEI quickly gained a reputation for excellence in the field of Land Surveying. Under new ownership, which includes current LEI President, Greg J. Zartman, P.E.,who worked under Mr. Hemphill's leadership for more than a decade, ushered in continued diversification, as LEI added civil engineering to its list of professional services in 2007. Recognizing that LEI was no longer a firm serving only the forest industry, but now a diverse firm providing industry leading services to city and county entities, the construction industry, state agencies and the forest industry – LEI became LEI Engineering & Surveying, LLC.
Today, LEI Engineering & Surveying’s mission is the same as it was at LEI’s inception more than 30 years ago:  Provide unparalleled professional services with a focus on client satisfaction. The LEI Engineering & Surveying team take pride in their rich history of engineering excellence and value as they stand ready today to address your civil engineering, construction engineering, forest engineering, forestry and land surveying project needs.
