Annelise Carleton-Hug

Annelise Carleton-Hug, doing business as Trillium Associates, is a self-employed sole proprietor operating as a self-certified small disadvantaged business that subcontracts on federal research and development programs, with all recorded federal work routed through prime contractors rather than direct prime awards. The vendor is based in Mill Run, Pennsylvania.

Trillium Associates' award footprint is minimal and recent. The source covers three sub-awards, all dated February 7, 2023, totaling $444 thousand in combined dollars obligated. All three sub-awards are with Science Systems and Applications, Inc. on the Support for Atmospheres, Modeling, and Data Assimilation (SAMDA) contract, with deliverables including monthly technical progress reports, invoices, health and safety reporting, and financial management reporting. The sole customer agency is NASA Goddard Space Center, accounting for 100% of recorded awards. The work falls under NAICS 541712 (Research and Development in the Physical, Engineering, and Life Sciences, except Biotechnology).

The vendor operates exclusively as a subcontractor and has not competed for prime contracts or IDVs in the source data. SCI-reported activity shows 0.2 FTEs delivered on a sub contract in FY2024, with no prime SCI records; this represents a narrow slice of the vendor's potential federal services activity and is consistent with a small, specialized contributor to larger research programs.

No activity appears in the source after February 2023, suggesting either the SAMDA sub-award work has concluded or Trillium Associates is not pursuing or receiving new federal awards. The vendor does not sit on government-wide vehicles, and no recompete cliff or forward-looking pipeline is evident from the current data. Competitive intelligence regarding Trillium Associates would depend on understanding Science Systems and Applications' SAMDA task-order strategy and identifying whether the vendor continues to support SAMDA under renewal or follow-on vehicles.
