What Delta Consulting does

Delta Consulting Group is a private, 100% employee-owned professional services firm headquartered in Woodbridge, Virginia, founded in 2000 as a boutique forensic and management consulting group. The firm operates four core service lines — Construction & Engineering, Disputes & Expert Testimony, Investigations/Forensics/Risks, and Project Advisory & Business Solutions — plus an Insurance & Recovery add-on practice. Service delivery spans forensic accounting and e-discovery, delay and quantum analysis, loss-of-productivity assessment, expert witness testimony for litigation and international arbitration, insurance claim preparation, fraud investigation, and cryptocurrency tracing, delivered by a multidisciplinary bench of engineers, accountants, forensic specialists, and project managers.

The firm operates from twelve offices across the United States (Woodbridge VA headquarters, plus San Ramon, Chicago, Englewood CO, Winter Garden FL, New York, and Dallas), Canada (Toronto, Calgary), the United Kingdom (London, Manchester), and Spain (A Coruña). It serves clients — including government agencies, global law firms, energy and infrastructure developers, and Fortune-scale corporates — in over 90 countries, with disclosed engagements spanning values from $80 million to $12+ billion (Panama Canal Authority, LNG Export Facility joint venture, Taiwan Nuclear, Volkswagen emissions matter, Raytheon class action, DHS Clarksville Data Center).

Revenue is generated through professional services consulting on a project-based and hourly fee model, sold via enterprise field sales, direct senior-professional engagement, referrals from law firm and corporate clients, and event-driven demand generation through AACE International, Society of Construction Law, and Paris Arbitration Week participation. Distribution is direct only — no channel partners — with standing U.S. federal access via GSA Schedule and SAM registration. The firm is a 100% ESOP (established 2018), is bootstrapped with no disclosed external funding, and pursues growth through a combination of organic office openings (UK 2019, Canada 2023, Spain 2025), a tuck-in acquisition of Froese Forensic Partners (2023), and credential accumulation (CIOB Chartered Member, RICS Regulated Firm).
