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 7 canonical listings in Columbia, Maryland; 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 are drawn from the NPPES registry and the Google Maps business listings behind the directory. The directory reports what each clinic publishes; it does not assess quality, and nothing here is medical advice.
