HENNINGSON, DURHAM & RICHARDSON P.C. is a legal services firm specializing in government contracting law, regulatory compliance, and procurement strategy. The firm provides expert counsel on federal acquisition regulations, bid protests, contract disputes, and compliance with FAR and agency-specific requirements. Their technical expertise includes navigating complex solicitation language, preparing and defending claims under the Contract Disputes Act, and advising on small business set-aside eligibility and subcontracting plans. As a law firm structured as a professional corporation, they deliver high-stakes legal representation tailored to federal contractors, with a focus on risk mitigation and contractual integrity. Award history is not available to determine specific agency engagements or recent contract performance. Consequently, no definitive patterns can be identified regarding their client base or the nature of their work with particular federal departments or agencies. The firm operates under NAICS 541330, which classifies legal services focused on specialized practice areas, including government contract law. In practice, this means they serve as strategic advisors to contractors navigating the federal procurement ecosystem, offering litigation support, compliance audits, and pre-award strategy development. Their market positioning is that of a niche legal provider for organizations requiring deep expertise in federal acquisition law, rather than general legal counsel. The entity is structured as a professional corporation (2L) and is headquartered in New York, NY. It holds no government certifications, such as 8(a), HUBZone, or WOSB. While geographically based in New York, its client base likely extends nationally, serving contractors across federal markets who require specialized legal representation in procurement matters. The firm’s value lies in its legal acumen and precision in interpreting complex regulatory frameworks governing federal contracting.
