About the company
Windsor Group LLC, an Economically Disadvantaged Women-Owned Small Business and SBA 8(a) certified firm based in Bethesda, Maryland, operates as a prime contractor delivering professional services and IT solutions to federal civilian agencies under set-aside and full-and-open vehicles, with recurring participation in 8(a) Sole Source and Competitive 8(a) awards alongside labor-hour and firm fixed-price engagements on the GSA Multiple Award Schedule.
Windsor Group holds concurrent certifications as a Women-Owned Small Business, Veteran-Owned Small Business, and Service-Disabled Veteran-Owned Small Business, and competes predominantly under 8(a) set-asides, particularly sole-source awards with the CDC, African Development Foundation, and International Development Finance Corporation. The vendor operates as a limited liability company structured as a for-profit organization and self-identifies as Black American owned and minority owned.
The vendor's capability portfolio centers on management consulting, administrative staffing, program management, grant management, statistical analysis, data science support, and executive advisory services. Representative work includes a $4.26 million 8(a) Sole Source definitive contract with CDC Pittsburgh (awarded July 2024) for National Center for Immunization and Respiratory Diseases comprehensive administrative support through July 2028; a $32.75 million Total Small Business delivery order with USDA Farm Production and Conservation (awarded May 2023) for regional hub staffing services in Regions One and Two; a $3.6 million 8(a) Sole Source purchase order with CDC for technical assistant support services (awarded March 2024, extending through February 2027); and a $100 million International Development Finance Corporation single-award indefinite delivery contract (awarded September 2023) for domestic and international staffing, program management, management consulting, and financial advisory services through September 2028.
Across SCI-reportable prime service contracts, Windsor Group invoiced $67.4 million from FY2022 through FY2025, with peak activity in FY2024 at $31.4 million across 593 FTEs. The workforce trajectory shows marked growth from 25.4 FTEs in FY2022 to 96.0 FTEs in FY2024, though FY2025 reported 50.0 FTEs, suggesting potential re-baseline or fluctuating labor utilization. Government-paid hourly rates across SCI-reportable work range from a 10th percentile of $44.91/hr to a 90th percentile of $184.99/hr, with median rates near $103.08/hr. GSA Schedule labor categories span 45 positions from Laboratory Technician at $34.87/hr through SME IV at $216.37/hr, all requiring bachelor's education with no security clearances offered.
Customer concentration anchors heavily with three agencies accounting for roughly 74 percent of recent award count. The International Development Finance Corporation leads on combined potential value at $108.5 million across 25 awards, followed by CDC Pittsburgh at $30.6 million across 33 awards and the African Development Foundation at $30.1 million across 33 awards. The Department of Agriculture accounts for $32.8 million in a single large regional hub contract, and the National Science Foundation's National Center for Science and Engineering Statistics holds $17.9 million across six awards. The International Trade Commission, Department of the Interior, Department of Veterans Affairs, Defense Media Activity, Missile Defense Agency, and National Science Board round out the active agency set.
Windsor Group holds seats on multiple federal vehicles. The GSA Multiple Award Schedule accounts for 84 task orders valued at $88.7 million. The vendor recently won four OASIS+ IDIQs—the OASIS+ 8(a) program (multiple-award, competitive 8(a) set-aside, $999 billion ceiling, ultimate completion November 5, 2029), OASIS+ Total Small Business (multiple-award, total small business set-aside, $999 billion ceiling, ultimate completion December 18, 2029), OASIS+ Women-Owned Small Business (multiple-award, woman-owned set-aside, $999 billion ceiling, ultimate completion September 29, 2029), and OASIS+ Service-Disabled Veteran-Owned Small Business (multiple-award, SDVOSB set-aside, $999 billion ceiling, ultimate completion September 29, 2029)—all awarded in September and December 2024 with five-year base periods and one five-year option. The vendor also holds a $16.2 million single-award Competitive 8(a) BPA with the African Development Foundation for professional services (awarded May 2024, 16 calls issued since award totaling $5.7 million). On November 1, 2026, NASA awarded Windsor Group a position on the SEWP VI multiple-award GWAC ($20 billion ceiling through October 2036) for IT communication and audio-visual solutions. Most significantly, the Missile Defense Agency awarded Windsor Group a position on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ ($151 billion ceiling through December 2035) on December 29, 2025, with an initial $500 delivery order for Huntsville, Alabama performance.
Activity has remained steady over the past three years—28 awards in 2022, 25 in 2023, 29 in 2024—though 2025 and 2026 year-to-date figures are incomplete (7 awards in 2025 and 13 in 2026 through November 1). Nineteen awards with ultimate completion dates inside the next twenty-four months carry combined potential value of $43.4 million, representing recompete exposure across CDC, IDFC, African Development Foundation, and USDA programs. Across SCI-reportable prime contracts, subcontractors performed an average of 12 percent of contractor hours, with 23 named subs engaged; Windsor Group self-performs the majority of delivery across its portfolio.
The vendor's award footprint is entirely prime (100 percent of recent awards are prime contracts or IDVs, with no subcontract work captured in the source). NAICS concentration runs toward Administrative Management and General Management Consulting Services (79 awards), All Other Professional, Scientific, and Technical Services (24 awards), and Human Resources Consulting Services (9 awards). PSC coding similarly emphasizes Support-Professional and Support-Management labor categories across administrative, program management, and human resources functions.
