Barry Rosenfeld

Barry Rosenfeld, a sole proprietor based in New York, New York, provides expert witness and litigative consultant services to the U.S. Attorney's Offices as a prime contractor on small purchase orders, competing on a full-and-open (non-set-aside) basis.

The vendor's entire federal footprint consists of four purchase orders awarded by the Department of Justice's U.S. Attorney's Offices between May 2025 and March 2026, totaling $81 thousand in combined potential value. All four awards carry time-and-materials pricing and target litigation support. The largest is a $35,300 expert witness purchase order for psychology services awarded May 20, 2025, with ultimate completion scheduled for May 19, 2027. Two additional litigative consultant purchase orders of $14,000 each were awarded November 28, 2025 (completion November 27, 2026) and January 28, 2026 (completion January 27, 2027). A third expert witness purchase order for psychology services worth $17,500 was awarded March 27, 2026, with completion scheduled for March 26, 2027. All work is performed in New York, NY. The vendor operates solely as a prime contractor; no subcontract work appears in the source.

Customer concentration is absolute — the U.S. Attorney's Offices account for 100% of recent awards by both count and dollar value. All four awards fall within the next twenty-four months' recompete window, representing $81 thousand in combined exposure. The vendor's work maps to NAICS 541900 (All Other Legal Services) and PSC code D304 (Support — Professional: Expert Witness) for three awards and D305 (Support — Professional: Legal) for one. Activity levels are nascent, with two awards in 2025 and two in 2026, and the vendor carries no vehicle positions or blanket arrangements.
