About our Founder – Dr. James Dragun

1949 – 2015 In 1988, with great passion, scientific acumen, and conviction, Dr. James Dragun founded The Dragun Corporation.  ShoDr-Drtly after he established the company, he released his first book, “The Soil Chemistry of Hazardous Materials.”  He would later go on to author or co-author many more scientific tomes including, “Elements in North American Soils” and “Natural Chemicals in Sediments.”

A native Detroiter, Jim completed his undergraduate work at Wayne State University in Chemistry, moving next to Pennsylvania State University where he earned a Master’s and Ph.D. in agronomy at his beloved Penn State.  The university recognized Jim’s accomplishments in 2005 when the Department of Agronomy awarded him with the Distinguished Alumni Award.

Upon graduation from Penn State, Jim served with the United States Environmental Protection Agency (EPA) in Washington D.C. Over the course of the next five years, Jim would work on some of the nation’s highest-profile environmental projects. It was while working for the EPA that Jim became convinced that a sound, scientific understanding of contaminants and how they behaved in the environment was lacking from many of the scientific assessments that he reviewed.

Realizing that his nature did not lend itself to be a government bureaucrat, Jim soon found himself working for environmental consulting firms in California and then back in his home state of Michigan later on. What Jim discovered during his time working for consultants was he wanted to approach projects differently than through industry standards. He believed that consulting meant solving problems as quickly as possible. As Jim was fond of saying, “We get you out of trouble, we keep you out of trouble, and we don’t make trouble.”

Over the course of the next nearly 30 years, Jim earned a well-founded reputation as one of the premier scientists in the environmental consulting community, known for his disciplined, scientific approach to solving complicated, environmental issues and conducting tough-as-nails regulatory negotiations. Jim was also a frequent lecturer in both the United States and Canada. Jim’s expertise in soil chemistry reached China, Europe, and the Middle East, where he was also invited to teach.

Jim’s scientific rigor carried over into the hand-selection of his team of scientists, engineers, accountants, and other staff members. He insisted that his “team” jealously guard the reputation of the company that bore his name.

In 2012, as Jim opted for semi-retirement and to pursue additional interests, he handed over management of the company to his trusted team, most of which had worked at Dragun Corporation for 25 years or more. That team continues to operate the company today with great deference to a strong foundation that Jim established and maintained throughout his lifetime. That legacy lives on.
