Thompson and Associates is a wetland services firm based in Wisconsin and Upper Peninsula Michigan that gives personal attention to every project, large or small — because every client matters. We celebrated our twentieth year in business in 2019.  Our expertise includes wetland delineation, wetland ecology and restoration, natural areas management, forestry, invasive species management, threatened and endangered species and wetland mitigation and permitting. 

Thompson and Associates were recognized as First Runner Up in the competition for Outstanding Woman-Owned Business Award, 2019 given by Governor Tony Evers. 

Alice Thompson, is an Assured Professional Wetland Delineator as determined by the Wisconsin Department of Natural Resources. Delineations that she performs do not require WDNR concurrence, and there will be no delay in using the results of her work in state waterway and wetland decisions. Complex or very challenging sites may still require local inspection by WDNR staff.
