Halpern, Joseph

Halpern, Joseph, a New York-based sole proprietor, provides expert witness services to the Securities and Exchange Commission on a time-and-materials basis as a prime contractor operating without set-aside designations or subcontractor engagement.

Halpern's federal footprint is narrow and specialized. All five prime awards in the source data flow from the SEC; no other federal agencies appear. The combined potential value across all awards is $1.5 million, with 100% of that amount obligated. Recent work includes a $250,000 definitive contract awarded May 12, 2026, for expert witness services with an ultimate completion date of May 11, 2031; a $260,000 contract awarded September 17, 2025, running through September 16, 2030; and a $41,437.50 engagement awarded November 22, 2024, completing December 3, 2025. All three contracts are priced on a time-and-materials basis and performed in New York, NY.

Activity is sparse and episodic rather than sustained: one award in 2014, one in 2019, one in 2024, one in 2025, and one in 2026. The vendor operates exclusively as a prime (100% of awards) with no subcontractor exposure across the portfolio.

Service Contract Inventory data covering federal service contracts above the $150,000 reporting threshold shows $56,000 in invoiced revenue across FY2022–FY2024 (FY2022: $25,000; FY2023: $31,000; FY2024: $0). The SCI dataset reports 0.0 FTEs across all three years, indicating that invoicing was recorded at the contract level without explicit FTE allocation — consistent with an independent expert or consultant model. On the SCI-reportable contracts captured, government-paid rates ran at a flat $340 per hour across all percentiles. No subcontractors appear in the SCI sub-engagement data. Halpern operates as a solo practitioner or one-person firm with no sub relationships and no demonstrated scaling into larger delivery teams or sustained staffing models.
