Dwayne embarked on a 40 year adult education career on April 1, 1948 with Iowa State College and the USDA Cooperative Extension Service. For seven years he worked in three Iowa counties as County Extension Director. His crop/soil education and research work in the last county culminated in the establishment of an Experimental Farm in Northwest Iowa. The Agronomy Department asked Dwayne to return to ISC, now ISU, for work on MS and PhD degrees during which time he served as an Area extension Agronomist and Extension Agronomist in Iowa.

Returning to Madison, he was given a split extension-research appointment. He chaired a committee that developed and adopted a new method of evaluating forage quality that has been adopted world wide and also chaired the UW Faculty Council that merged the tenure systems of the UW and the State University System institutions. During his career, Dwayne trained 17 graduate students at the MS level and 1 at the PhD level.
