How we built this guide

The figures below come straight from the Sleep Clinic Directory database, counted on November 4, 2026.: the clinic count from the 583 canonical listings in California, split by the 203 cities they sit in; 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. Clinic details come from the NPPES registry and the Google Maps business listings the directory is built on. The directory lists what each clinic publishes — it does not assess quality, and nothing here is medical advice.
