William B. Zucconi

William B. Zucconi, a sole proprietor based in Madison, Connecticut, provides expert witness testimony and litigative case support to the Department of Justice's Civil Division as a full-and-open prime contractor, competing without small business set-asides. All work is performed directly by Zucconi without subcontractors.

Zucconi's entire federal footprint consists of 22 purchase orders awarded exclusively by the DOJ Civil Division since November 2021. The work is categorized under PSC "Support—Professional: Expert Witness" and NAICS "Offices of Physicians (except Mental Health Specialists)" (18 awards) and "All Other Legal Services" (4 awards). Individual contract ceilings range from $2,725 to $35,791, with most clustering between $13,000 and $16,000. Representative awards include a $14,991 time-and-materials purchase order issued August 11, 2026 for expert witness and litigative case support with ultimate completion August 10, 2029; a $31,866 contract awarded September 26, 2023 for expert witness testimony on complex federal litigation; and a $35,791 contract issued November 10, 2021 under Executive Order 14042. All 22 awards carry time-and-materials pricing and two- to three-year performance periods.

The Civil Division represents 100% of Zucconi's award count and combined potential value ($295 thousand). Award volume has been modest and uneven—five awards in 2022, five in 2023, two in 2024, four in 2025, and three in 2026. Eight awards with ultimate completion dates in the next twenty-four months carry combined potential value of $154 thousand, representing 52% of his active portfolio and therefore material recompete exposure. Zucconi has obligated $295 thousand across all awards, indicating sustained utilization of contract ceilings across his portfolio. His relationship with the Civil Division demonstrates consistent demand for specialized expert witness expertise in support of federal litigation, with no involvement in IDIQs, GWACs, or other parent vehicles.
