J.S. HELD LLC

J.S. HELD LLC specializes in providing expert witness and technical consulting services to federal agencies, with a dominant focus on litigation support and specialized forensic analysis. The firm delivers high-stakes expert testimony in areas including accident reconstruction, economic analysis, and financial forensic evaluation, often supporting complex civil and criminal proceedings. Their technical expertise spans engineering-based incident analysis, economic modeling, and accounting forensics, enabling them to translate technical data into legally admissible testimony. Key differentiators include deep domain specialization in niche scientific and economic disciplines, a proven ability to interface with legal teams under tight litigation timelines, and consistent delivery of court-ready reports and deposition support. The contractor maintains a strong, enduring relationship with the Department of Justice, where the majority of engagements center on expert witness services for litigation involving economic damages, forensic accounting, and engineering failure analysis. Limited but notable work has also been performed for the Securities and Exchange Commission and the Department of Defense, typically involving technical assessments requiring expert testimony in regulatory or operational contexts. This pattern suggests a reputation for reliability in high-compliance, high-stakes legal environments. J.S. HELD LLC operates primarily under NAICS 541690 (Other Scientific and Technical Consulting Services) and 541199 (Other Legal Services), positioning itself at the intersection of technical analysis and legal advocacy. Their market niche is the provision of expert testimony services across civil, criminal, and regulatory proceedings, serving as a bridge between complex technical domains and judicial processes. The firm is structured as a 2L entity based in Jericho, New York, with no publicly disclosed government certifications. Its geographic presence is centralized in the Northeast, with a federal market focus driven by proximity to major litigation hubs and federal courts. The company’s positioning is that of a specialized, boutique provider of expert witness services rather than a broad-based consulting firm.
