Environmental, Energy & Natural Resources
Environmental, energy, and natural resource disputes often involve highly technical scientific and regulatory issues — the kind that require an expert witness who understands both the science and the legal context. Intellex has been connecting attorneys with credentialed environmental and energy experts since 1984, for both plaintiff and defense matters.
Whether your case involves EPA enforcement, site contamination and remediation, an energy sector dispute, or a natural resource claim, your Intellex advisor will identify and vet the right expert. If your specific environmental or energy specialty isn’t listed here, we’ll find them.
