The citable document for SERENETHOS CARE CENTER, LLC
This page shows the record as it stands today. The report is the citable document: the same figures with the cell each came from, and beyond this page — five facilities of a similar size in California at the same fiscal year, listed by name; every change on the record rather than the recent ones below; the inspection and staffing history in blocks of their own; and a citation block naming every CMS file it was read from.
Every figure on this page is printed as it appears in the CMS file named beside it. A figure that does not match its file? Tell us on the corrections page, quoting certification number 555905.
