The Hardenbergh Group owns healthcare services firm Sentact, serving top US health systems with credentialing, peer review, and consulting.
The Hardenbergh Group
The Hardenbergh Group is a family office that owns and operates healthcare services companies rather than deploying capital through external funds. Its primary holding is Sentact, a firm that provides credentialing, privileging, enrollment, and external peer review services to US health systems. The office maintains offices in Tampa, Grand Rapids, Livonia, and Nashville. The group's strategy centers on healthcare operations, primarily through Sentact. Sentact's Credentials Verification Organization (CVO) handles interim staffing and provider enrollment, while its external peer review unit draws on a network of over 450 board-certified physicians across all specialties. The firm also offers consulting services focused on operational excellence and leadership development for health systems. Its client base includes many of the top 20 largest US health systems. The Hardenbergh Group lists no public AUM or team size. Its structure as an operating-company owner rather than a fund manager means it does not disclose deployment metrics typical of investment offices. The group hosts an annual Senior Medical Staff Leader Forum for health system executives; details for the 2027 forum were not yet published as of mid-2026. The group's structural differentiator is its operating-company model: rather than writing checks to external managers, it builds and scales a single healthcare services business through Sentact. This approach ties family capital directly to operational outcomes, yielding a concentrated portfolio that depends on organic growth and acquisitions within credentialing and peer review.
