The Nielsen Environmental Field School

Established in 1990 by company principals David M. Nielsen (a geologist and hydrogeologist) and Gillian L. Nielsen (a hydrologist and aquatic biologist), The Nielsen Environmental Field School quickly became the leading provider of practical, hands-on environmental field training in the world. Times have changed, and so have we! In 2015, in celebration of our 25th anniversary of offering top-quality practical environmental training, we video-recorded all of our `live` field courses and converted them to an on-line, distance-learning format, in the form of The Nielsen Environmental E-School. The E-School replaces our `live` open-enrollment courses. All of our former open-enrollment courses are now available exclusively on-line so that anyone, anywhere in the world can take any of our E-Courses or E-Modules, as long as they have a computer or tablet and Internet access.
