Jeff Duncan, PG

Jeff Duncan moved to Richmond, VA from Atlanta, GA with a stop at a rural Oklahoma town along the way.  He studied Geology at Old Dominion University and completed his Masters of Environmental Science at Oklahoma State University.  He went on to refine his expertise by getting knee-deep in assessment and remediation work in various voluntary clean-up programs.  Passionate about his work, he took his experience and then managed a consulting office in Atlanta, GA. He then made the decision to move back to his hometown in Virginia where he is “living the dream” as a founding Principal at ONE performing consulting services from our Tidewater office.  In his free time, Jeff may be on the golf course perfecting his swing. If he is not out on the greens, he may be out on the Chesapeake Bay casting his fishing line. Most importantly, he enjoys spending time with his family and three children.

More about Jeff:

Jeff has over 17 years of environmental consulting experience supporting the Mid-Atlantic region.  He has performed environmental consulting within multiple regulatory agencies including Underground and Aboveground Storage Tank Programs, RCRA, Superfund, Solid Waste, Brownfields, and Voluntary Programs. He has worked with clients in the chemical, financial, legal, pulp and paper, foundry, petroleum, transportation, manufacturing, aggregate, real estate and food industries.
