The firm delivers comprehensive environmental due diligence, landfill repair, waste management, and occupational health services—including employee assistance programs, fitness assessments, and medical employability support—tailored to high-security federal operations. Their technical proficiency spans environmental health standards under PWS 5.3, regulatory adherence for aerospace and defense installations, and integrated medical services aligned with NASA and DoD protocols.

For NASA, they provide environmental due diligence for launch facilities and medical services for headquarters personnel. For the DoD, they deliver environmental health support to naval ordnance units and space launch operations, often under tightly constrained security and compliance frameworks. Their relationship with these agencies reflects a trusted, recurring partnership focused on high-stakes, technically demanding assignments requiring precision and regulatory rigor.
