Turnbow Diana Lynne

Turnbow Diana Lynne, a woman-owned sole proprietorship based in Vienna, Virginia, provides research, fact-checking, and administrative support services to the Smithsonian Institution as a prime contractor, competing exclusively in full-and-open procurements without set-aside designation.

The vendor operates as a sole proprietor with an active federal contracting status dating to November 2017. All four recent awards derive from the Smithsonian Institution and its Office of the Chief Financial Officer, with no subcontract footprint. The vendor's work concentrates on women's history content support — research and fact-checking for the American Women's History Museum and the American Women's History Initiative, as well as administrative assistance to those programs. Customer concentration is absolute: the Smithsonian Institution accounts for two awards totaling $160 thousand in combined potential value, and the Smithsonian Institution Office of the Chief Financial Officer accounts for the remaining two awards totaling $107 thousand, representing 100% of the vendor's recent federal award portfolio. The vendor carries primary NAICS assignments in All Other Professional, Scientific, and Technical Services (three awards) and All Other Support Services (one award).

Activity is sparse and episodic — one award per year from 2021 through 2025, with a combined potential value of $267 thousand across all four awards. All dollars have been obligated. Recent representative work includes a $84.5 thousand firm fixed-price purchase order for research and content services awarded October 9, 2025 with completion targeted for October 9, 2025; a $75 thousand labor-hours purchase order for FY24 Smithsonian American Women's History Museum research and fact-checking services awarded June 14, 2024 with completion targeted for November 30, 2025; a $62.4 thousand firm fixed-price purchase order for research and administrative services supporting the American Women's History Initiative awarded January 25, 2023; and a $45 thousand purchase order for administrative assistance to the American Women's History Initiative awarded September 16, 2021. All awards carry performance in Vienna, Virginia. The vendor's relationship with the Smithsonian spans specialized expertise in women's history research, curatorial support, and institutional program administration, with no documented federal customer diversification.
