About Us

The Nielsen Environmental Field School was created in 1990 in response Dave Nielsen teaches environmental field school in Guatemalato a demand from the environmental industry for practically oriented, hands-on environmental field training. Twenty-five years later, in 2015, The Nielsen Environmental E-School was created in response to a demand from our clients, students and other environmental professionals for an affordable and highly accessible web-based form of training that incorporates all of the technical content of our popular field courses.  The E-Courses offered through the E-School effectively replace the open-enrollment courses historically offered by the Field School.  As of September 2015, the Field School is no longer instructing "live" courses on an open-enrollment basis. 

The Nielsen Environmental E-School offers a comprehensive series of professionally prepared E-Modules and E-Courses that provide students with the latest information on the tools, technologies, field practices and methodologies available in the environmental industry that can be used on the job immediately.  The Field School's and E-School's  principals and key instructors, David M. Nielsen and Gillian L. Nielsen, who possess a unique combination of more than 75 years of environmental field experience and more than 70 years of International teaching experience, instruct all of the E-School's individual training modules and E-Courses.
