“For forensic work, I would start with Dragun, and I would recommend others do as well.” – Lawyer

Environmental Expert Witness Services

The question of “who pays?” is a sensitive one for companies embroiled in litigation and high-stakes negotiations. When faced with settlement fees, court judgements, or fines tied to environmental issues, you need a team that has the scientific “chops” to successfully challenge questionable allegations. Whether they be from state or federal regulators, mega-size consulting firms, large corporations, the US Army Corps of Engineers, or even state and federal Supreme Courts. Dragun has “been there and done that”… successfully for 35 years.
