IDPH licenses Three Oaks Assisted Living for 87 assisted living units: 62 regular assisted living units, 25 Alzheimer's/dementia special care units. About 29% of the licensed units are dedicated to Alzheimer's care, so dementia support is a meaningful part of its program.
Illinois licenses assisted living by living unit rather than by bed. An Alzheimer unit belongs to a special care program for people with Alzheimer's disease or a related dementia, which the Assisted Living and Shared Housing Act (210 ILCS 9) and 77 Ill. Adm. Code 295 hold to added staffing, training and environment requirements.
The licensee of record for Three Oaks Assisted Living is Cary Senior Living, LLC. IDPH shows 4 license period(s) for this establishment in its online system, the earliest beginning October 30, 2023, and no change-of-ownership record at this address.
IDPH's online system only reaches back to its 2023 migration, so a community can be licensed far longer than the earliest period shown; ask the community when it first opened.
None are posted. As of October 23, 2026, the IDPH public lookup lists no survey reports, violations or enforcement actions for Three Oaks Assisted Living. That reflects what IDPH publishes online, not a guarantee that no survey has taken place.
