Sundance Consulting

What Sundance Consulting does

Sundance Consultants, LLC (formerly Sundance Consulting, Inc.) is a Pocatello, Idaho-headquartered environmental consulting firm founded in 2005 by CEO September Myres to remediate contamination from Department of Defense activities on Tribal lands. The firm delivers an interdisciplinary professional services portfolio across eight capability lines: Environmental Compliance, Site Characterization & Remediation (including PFAS characterization), Natural Resources, Planning & Permitting (NEPA/CEQA), Cultural Resources Management, Public Involvement & Tribal Liaison Services, Digital Solutions (environmental data management and GIS deployment), and Staff Augmentation. Service delivery is anchored by 95+ professionals — archaeologists, biologists, ecologists, engineers, geologists, GIS specialists, hydrologists, and toxicologists — credentialed across CPG, PG, CHMM, and EPA-approved auditor designations, with cumulative delivery exceeding 220 site assessments across 92 remote Alaska/Aleutian sites and 194+ permits at Naval Base Guam/Andersen AFB since 2015.

Sundance's revenue model is professional services billed predominantly through federal contracting vehicles — most importantly the GSA OASIS Small Business Pool 1 contract (47QRAD20D1068) — supplemented by direct agency task orders with USACE, USAF, NAVFAC, BLM, USFS, USFWS, EPA, Bureau of Reclamation, BIA, NREL, and Sandia National Laboratory. Pricing supports all standard FAR contract types (FFP, T&M, cost, hybrids) with a 0.75% Contract Access Fee (reduced to 0.1% for DoD customers under MOU). Customer mix is roughly 70%+ federal defense and civilian, with growing tribal, state/local, and commercial exposure.

In 2024 the firm was acquired by True Environmental, a Halle Capital Company, joining a national platform of 700+ environmental and engineering specialists across 25+ offices. Sundance retains its brand and contract vehicles within the platform, gaining access to expanded service offerings through partner firms (Matrix Solutions, Triton Environmental, Sphere 3 Environmental, Great Ecology, GKY, Ensero Solutions, Padre Inc.) for vertical expansion into coastal resiliency, water/wastewater, and remediation design.
