What this page is. A view of the public federal registry, nothing more. An NPI record shows that an organization registered an address under the Behavior Analyst taxonomy code. It does not show that the location is open today, that it is currently accepting clients, or anything at all about the quality of care. Registration is not endorsement.

Where the data came from. The CMS NPPES full replacement file dated 12 July 2026, filtered to organizations only — individual practitioners are excluded from this site by design. Where a company publishes its own list of locations we show it above the registry table and cite it to the company — a registered address is where an organization is enumerated, not necessarily where it sees children. Where a company trades under a different name from the one it is registered under, we show the trading name and cite it; the registry's own doing-business-as field is redacted in the downloadable file, so those names are added one at a time from the company's own sources. Records grouped where the registered organization name matches. A company may operate under names we have not grouped together, and a registered address may be an administrative office rather than a clinic.
