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 from the 145 canonical listings in Maryland, split by the 58 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.
