– Certified as a Professional Wetland Scientist (PWS) by the Society of Wetland Scientists since 1995


Since establishing The Resource Company (TRC) in 1991, Mr. Grosz has been involved in over 1,500 natural resource studies that vary from wildlife habitat studies to wetland delineations and mitigation planning to stream and riparian zone restoration projects for private and public-sector clients in Washington and Oregon. Most of these projects have required permitting with local, state and federal regulatory agencies. In addition, a majority of these projects have required the preparation of mitigation plans including monitoring and maintenance components. Recent wildlife and fish work has included studies on threatened, endangered and species of concern for road projects, rock mining and development purposes (residential, commercial, retail). He is well acquainted with the Corps of Engineers’ regulatory policies requiring wetland evaluations and has extensive experience in using the 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys and Coast Region. In addition, he is the administrator of one of only a few wetland mitigation banks located in the state of Washington.

Prior to establishing The Resource Company in 1991, Mr. Grosz worked as a Wetlands Ecologist for Wallis Engineering in Vancouver, Washington. From 1988 to 1990, he worked for the U.S. Army Corps of Engineers as an Outdoor Recreation Planner at Corps Headquarters in Washington, D.C. and as a Wildlife Biologist at the Waterways Experiment Station (WES) in Vicksburg, Mississippi. At Corps Headquarters, he participated in formulating and interpreting natural resource regulations for Corps water resource projects. As a Wildlife Biologist at WES, he provided technical assistance to Corps field offices on wetlands and waterfowl habitat management.

From 1987 to 1988, he worked as a Research Assistant at North Dakota State University (NDSU) where he conducted applied research, primarily on wetland and water resource development issues. Prior to his work at NDSU, Mr. Grosz held wildlife biologist positions with the U.S. Fish and Wildlife Service, North American Coal Corporation, and North Dakota Game and Fish Department.
