Caliburn International

What Caliburn International does

Caliburn International, operating commercially under the Acuity International brand, is a private professional services company headquartered in Reston, Virginia that delivers integrated government services to federal, state, local, and international agencies worldwide. The firm is structured around eight core service lines: Program & Construction Management, Environmental Remediation, Security Services, Base Operations & Facilities Management, Occupational Health Services, Medical Services, Emergency & Disaster Response & Recovery, and Civil Services. It positions itself as a "single source provider" combining capabilities consolidated from five predecessor entities — Comprehensive Health Services, Janus Global Operations, Project Time & Cost (PT&C), Michael Baker Global Services, and Sallyport — to deliver what it describes as "integrated mission solutions," "global health solutions," and facilities management in demanding environments.

The company's operating model is a managed-services, prime government contracting business: revenue is generated through direct bids and negotiated contracts with government agencies across multiple geographies and program types, including healthcare delivery, occupational health screening, emergency response, environmental remediation, security, and base/facility operations. Pricing is not publicly disclosed and follows the standard federal/RFP contracting model. Go-to-market is enterprise field sales supplemented by content marketing (blog, resource library, brochures, case studies), event participation (AOHC 2026, SAME SBC 2025), a dedicated client login portal (cp.chsmedical.com), and a formalized diverse-supplier teaming program partnering with small, veteran-owned, woman-owned, and minority-owned businesses. The customer base spans the Federal Government as the primary segment, with State, Local, and International Governments as secondary segments, plus specialized work for Department of Corrections agencies (on-site medical examination and program management for new-hire and employee medical/physical exams).

Technically, Acuity advertises use of "advanced technologies" for large-scale program and project management in global, high-stakes environments, but the source material discloses no proprietary AI/ML, data platform, or specific technology stack beyond that general framing. The workforce is described as "peerless talent" aggregated from the legacy entities, and the leadership team publicly identified includes Jim Van Dusen as Chief Executive Officer and Jerry Chernock as Director. The company is privately held with 5,001–10,000 employees, founded in 1996, and actively recruiting via its careers portal.
