How we built this guide

Every statistic here is a count taken from the Sleep Clinic Directory database on November 4, 2026. The clinic count comes from the 5 canonical listings in Marion, Illinois; accreditation from the credential recorded for each listing; ratings and review counts from the Google Maps match for each clinic; and services from the service labels each clinic publishes. Records come from the NPPES registry and Google Maps business listings. Each listing shows what the clinic publishes; the directory does not assess quality, and none of this is medical advice.
