What The NMAS Group does

The NMAS Group (National Multi-Advisory Services Group) is a Maryland-based, privately held expert consulting firm established in 1982 and operating as a division of Building Health Sciences, Inc. The firm delivers five interconnected service lines to enterprise clients across the United States: environmental insurance claims consulting (moisture intrusion, mold, Legionella, asbestos, petro-chemical incidents, fire/smoke damage); litigation support and advisory services including expert witness testimony, construction defect analysis, surety bond claims, and forensic accounting; financial, accounting, and operations advisory; building science and indoor environmental quality delivered through sister company Building Health Sciences; and alternative dispute resolution including private arbitration and mediation. Customers include environmental insurance carriers, legal counsel, construction contractors and sureties, healthcare systems, REITs, and US government entities including military housing at Camp LeJeune and Cherry Point.

The firm's underlying capability rests on multidisciplinary human expertise — business owners, licensed contractors, tradesmen, and construction accountants — rather than on technology platforms. Differentiated offerings include forensic cost and scope assessment with documented accuracy/precision, industrial hygiene and indoor environmental services integrating building and occupant health, and credentialed ADR services through long-standing AAA National Roster of Neutrals membership and Maryland Rules Title 17 compliance. Notable documented outcomes include uncovering approximately $4M in CEO theft, $1.4M in partner theft, achieving ~20% Workers' Compensation premium savings for a government facility management contractor, and overseeing a 1,952-unit military housing mold assessment post-Hurricane Florence.

NMAS generates revenue through project-based professional services fees billed per engagement, with quote-based pricing tied to scope of work rather than published rate cards. The go-to-market is enterprise field sales — direct consultative engagement with insurance carriers, legal professionals, construction firms, healthcare systems, and government entities — supported by a professional website and referral-driven reputation rather than digital demand generation. No public pricing, no disclosed revenue, and no external funding rounds appear in the available data.
