Our History

Forestry is in our genes.

The Steigerwaldt name has long been a fixture in North American forestry. Ed Steigerwaldt Sr., a University of Michigan forestry graduate, founded the company. Ed Sr. served as the head of Wisconsin Department of Natural Resources Forest Inventory before launching Steigerwaldt.



In 1957, Edward F. Steigerwaldt Sr. established a forestry consulting company in the northwoods of Tomahawk, Wisconsin. A man of great energy and enthusiasm, Ed Sr. saw the need for forest product marketing. He designed his business to emphasize forest management, timber sale facilitation, aerial photograph interpretation, and general land consulting.

ed-seniorHis son, Ed Jr., joined the company in 1970, creating Edward Steigerwaldt & Son, Consulting Foresters. Expanding the business to include timber inventory and real estate appraisal, they successfully completed a succession of notable inventory and mapping projects throughout Wisconsin and Michigan. The business gained a reputation for high-quality work and a commitment to forest stewardship.

With expanded services and the addition of staff members, the company name was changed to Steigerwaldt Land Services, Inc., (SLS) in 1987. The next year, SLS further diversified to offer right-of-way appraisal and acquisition services, which has remained an active and vital area of the business. Shortly thereafter, SLS became the first forestry consulting firm to introduce Geographic Information Systems (GIS) services and has been at the forefront of this technology ever since. Today, our complete range of forest and real estate services make SLS the only single-source land services company in the Lake States region.

Along with the third generation of Steigerwaldts, the original vision for superior land management, established over half a century ago, is today upheld by an exceptional staff of foresters, appraisers, GIS specialists, and real estate professionals who have the highest respect for our natural resources and an unsurpassed dedication to client satisfaction. See for yourself how SLS continues to set the standard for environmental professional excellence.
