What this means

Roles are shown as CMS publishes them. Different CMS sources can describe different enrollment, ownership, and control concepts, so TrustHub keeps each source-specific disclosure distinct.

Questions to ask

CMS records list several organizations with ownership or control roles. Which entity is responsible for day-to-day operations at this facility?
CMS records connect OMNI MANOR, INC. to 11 facilities. Which policies and staffing decisions are managed centrally versus locally?

Chain context

CMS groups this facility with WINDSOR HOUSE, INC.

Chain-level values describe this CMS-defined group, not any one facility. CMS Chain ID 567 is a grouping identifier, not a legal organization.

Facilities: 11
States and territories: 1
