Health inspection rating: ★★★★★5/5 · CMS overall rating: 5/5 · how star ratings work →
The health inspection star above is graded on a curve within each state — a set share of each state's facilities gets each star level — so a facility can have few citations and still rate 2–3 stars if others in its state did even better. The overall rating combines that inspection score with staffing and quality measures from resident assessments and claims.
Most serious findings (actual harm or immediate jeopardy)
▲ Immediate jeopardy, widespread · Dec 16, 2022 · F-0801
The facility did not employ enough qualified food and nutrition staff, including a qualified dietician, to properly run its food service.
▲ Immediate jeopardy, widespread · Dec 16, 2022 · F-0801
The facility did not employ enough qualified food and nutrition staff, including a qualified dietician, to properly run its food service.
Why it matters: Without qualified nutrition staff, residents' special diets and nutritional needs may be handled incorrectly, risking weight loss and health decline.
Severity (L): Immediate jeopardy to resident health or safety was cited. The scope was widespread: a systemic or pervasive problem. Scope describes the extent of the deficiency, not whether it happened on previous inspections.
Corrected: Feb 9, 2023 (Deficient, Provider has date of correction)
▲ Immediate jeopardy, isolated · Dec 16, 2022 · F-0726

▲ Immediate jeopardy, isolated · Dec 16, 2022 · F-0726

Why it matters: Undertrained caregivers are more likely to miss warning signs and make care mistakes.
Severity (J): Immediate jeopardy to resident health or safety was cited. The scope was isolated: limited residents, staff, or locations were affected. Scope describes the extent of the deficiency, not whether it happened on previous inspections.
Corrected: Feb 9, 2023 (Deficient, Provider has date of correction)
▲ Immediate jeopardy, isolated · Dec 16, 2022 · F-0800
The facility did not provide each resident with a nourishing, tasty, well-balanced diet that meets their daily nutritional and special dietary needs.
▲ Immediate jeopardy, isolated · Dec 16, 2022 · F-0800

Hours are per resident per day for the most recent quarter of payroll data in this CMS release (2026-08-01) — the same quarter for every facility — case-mix adjusted by CMS so facilities caring for sicker residents can be compared fairly (same basis as the CMS staffing star). "Top X%" means better than most facilities: more staffing hours, or lower turnover. Raw (unadjusted) reported hours: total 3.99, RN 0.38, weekend 3.75.Comparing with Medicare Care Compare? Care Compare shows the raw figure (3.99 here, displayed there as hours and minutes), not the adjusted one above. Both are correct; they answer different questions. Staffing rating: 3/5.
Quality measures: assessments & claims
Note: CMS combines facility-reported resident assessments (MDS) with claims-based measures. These are different sources from on-site inspection findings. Read the measures alongside inspection and staffing records; a high QM rating does not establish that a home is safe.

Costs & payment
Price evidence · separate from quality
No verified facility-specific private-pay price is available in our data for Serenethos Care Center, LLC. CMS inspection and staffing records do not tell us what this home will charge you.
Calculate a stay from a quote you receive
Use a written private-pay quote. This worksheet adds only the amounts you enter; it does not calculate Medicare, Medicaid or insurance benefits.
Formula: (room rate + daily extras) × days + one-time charges. A 30-day scenario is not a calendar-month quote. Refundable deposits, rate changes and charges you omit are not automatically included. Entries are not saved or sent to our server.
Before you compare prices
- Request the room type, effective date and itemized daily rate in writing.
- Ask about therapy, medicines, supplies, care-level charges, deposits, refunds and annual increases.
- Confirm insurance or Medicaid eligibility and bed availability directly; certification alone does not guarantee either.
