Thunderbird Environmental LLC

What Thunderbird Environmental LLC does

Thunderbird Environmental LLC is a Clinton, Connecticut-based environmental consulting firm founded in July 2014 by Darby Hittle, a United States Air Force veteran. The company delivers a full suite of environmental services including Phase I, II, and III environmental site assessments, NEPA documentation and ecological studies, remedial investigation and oversight, industrial hygiene and safety support, stormwater management and NPDES permitting, underground storage tank removal oversight, hazardous building materials surveys, permitting and compliance, and USDA NRCS Emergency Watershed Protection (EWP) Program sponsor support. Its primary customers are federal government agencies — including the VA, USDA NRCS, National Park Service, US Forest Service, US Army Corps of Engineers, US Fish and Wildlife Service, Department of Interior, Bureau of Land Management, and Department of Defense — with a smaller secondary base of private sector clients requiring property transaction due diligence and compliance work.

The firm operates as a credentialed professional services practice with no proprietary software platform or technology product. Its technical edge rests on staff qualifications: Licensed Environmental Professionals (LEP), Certified Industrial Hygienists (CIH), a PhD-level senior scientist, and NOAA-approved Protected Species Observers support coastal construction engagements. NAICS codes 541620, 562910, and 611430, along with CAGE Code 76A02 and DUNS 079478287, reflect standard federal procurement registrations. The company holds SBA SDVOSB certification via the VA Center for Verification and Evaluation, plus state SDVOSB/MBE certifications in Connecticut, Massachusetts, and New York. It was recognized as USDA NRCS SDVOSB Contractor of the Year in 2017.

The business model is project-based professional services revenue delivered through direct federal contracting and on-call/IDIQ engagements, with go-to-market centered on direct outreach to agency procurement staff, participation in SAME Federal Small Business Conferences, and an online presence via its website and LinkedIn. The company moved to its current larger headquarters at 13 Heritage Park Road in Clinton, CT in May 2019, and as of 2024 employs a team spanning founders, senior technical staff, environmental scientists, field technicians, and a marketing/business development function. Revenue is not publicly disclosed.
