CMS National Plan & Provider Enumeration System (NPPES) NPI Registry, live registry (individual providers, county). Retrieved 2026-07-23. Providers self-report NPPES records, so an address or phone number can lag a practice move — confirm details directly with the office. An NPI is a federal enumeration, not a license status, quality rating, or endorsement.

About this page

This is a data profile assembled from public sources — the CMS NPPES NPI Registry and U.S. Census market data — not the practice’s own website, and not a ranking. Inclusion is automatic for every active registered dentist in a covered city; no practice can pay to appear, disappear, or rank. Patients should verify hours, availability, and insurance participation directly with the office. See our methodology.
