The Inland Empire recorded 198 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The registry lists 124 new providers this week and 130 new providers this year. Its records include 187 individuals and 11 organizations, signaling substantial workforce activity across a large regional market rather than a provider base concentrated only in corporate entities. NPI registrations do not confirm active caseloads, staffed locations or available appointments.

ABA Credential Mix

The update identifies 7 BCBA providers and 70 RBT providers, with 2 dual credentials covering both BCBA and RBT status. These categories overlap, so the dual-credential providers are counted in both totals and should not be added as a separate workforce group. The credential mix shows a large direct-care workforce alongside a much smaller pool of potential clinical supervisors. That imbalance can constrain supervision capacity as clinics add RBTs, even when overall staffing appears to be expanding. Credential and taxonomy categories are not mutually exclusive; 37 providers have multiple taxonomies, so classification totals should not be treated as distinct shares.

Workforce Demographics

Women account for 143 providers, or 76% of the reported workforce. Men account for 26 providers, or 14%, and nonbinary providers account for 18 providers, or 10%. No notable organization appears multiple times in the update. Colton leads the listed cities with 49 providers, followed by Riverside with 32, Rancho Cucamonga with 17, Ontario with 15 and San Bernardino with 13. Overall, the data points to expanding ABA access in the Inland Empire, but sustained growth will depend on building BCBA supervision capacity alongside its RBT workforce.
