The Bay Area has 325 providers in the latest CMS NPI registry weekly update, representing 3% of the national weekly total. With 185 providers listed as new this week, the region accounts for a substantial concentration of registry activity. NPI records do not confirm that providers are actively practicing, accepting patients or delivering ABA services.

ABA Credential Mix

The registry lists 7 BCBA providers and 143 RBT providers, with 4 dual credentials shared across both counts. These categories overlap and are not mutually exclusive. The much larger RBT listing points to a technician-heavy profile, while the smaller BCBA count suggests a comparatively limited pool of listed supervisors. That contrast matters because BCBAs supervise RBTs, though the registry does not establish current job duties or supervisory relationships. A further 92 providers have multiple taxonomies, another reason not to treat credential and taxonomy counts as separate workforce shares.

Workforce Demographics

Women account for 196 providers (68%), men for 60 (21%), and nonbinary providers for 34 (12%). The percentages are reported separately and may not total precisely 100% because of rounding. No notable organization appears multiple times in the supplied data. San Jose leads the listed cities with 41 providers, followed by Concord with 36, Oakland with 29 and San Francisco with 25; no city is flagged for headquarters-registration skew.

The update suggests broad provider activity across the region, but the imbalance between listed RBTs and BCBAs highlights the importance of supervisory capacity for sustaining ABA access as the workforce grows.
