HLMI is an unpopulated LLC; therefore, all staff are employed by either Navarro or ATL. Both companies benefit from the historic knowledge and contributions of incumbent staff, who are critical to maintaining relationships with other Hanford contractors, union labor forces, and other organizations working to achieve DOE’s Hanford Site mission.


HLMI managing partner Navarro is one of the largest and most successful award-winning small businesses working in the DOE complex. Navarro has the systems, processes, and significant experience managing large and complex projects of over $400M in size. Navarro has a strong technical background and more than a decade of experience in managing Hazard Category 3 nuclear facilities and providing nuclear safety expertise to DOE’s Richland Office and other DOE and contractor clients across the DOE complex.

ATL, a wholly owned subsidiary of Planned Systems International, Inc. (PSI), is another award-winning small business that brings to their clients innovative scientific and technical solutions of the highest quality in the fields of health, environment, and analytical services. ATL is recognized for its proven expertise in radiology, occupational health and safety, nuclear and laboratory operations, decommissioning and demolition, and information technology. ATL has over 25 years of Hanford experience and 30 years providing radiological laboratory services, which includes over 11 years providing effective analytical services at the 222-S Laboratory. During that time, ATL achieved Voluntary Protection Program Star status, the first small business prime supporting DOE to do so. ATL will continue its commitment to safely delivering quality analytical results on time to support the Hanford Site mission.

Worl class contractor Amentum was selected as HLMI’s critical subcontractor based on its outstanding and extensive experience in engineering, nuclear operations, and facility maintenance, including their work at the 222-S Laboratory. Amentum will provide nuclear safety support and the engineering capability to perform the major facility improvements at the 222-S Laboratory. Both Navarro and ATL have proven, successful working relationships with Amentum.
