Central Valley recorded 249 providers in the latest CMS NPI registry weekly update, representing 3% of the national weekly total. The update includes 137 new providers this week and 153 added this year. Records cover 239 individuals and 10 organizations, signaling a sizable and rapidly expanding regional workforce presence. NPI records do not establish whether a provider is actively practicing, accepting patients, staffing a site or offering ABA services.

ABA Credential Mix

The registry identifies 13 BCBA providers and 123 RBT providers. These categories overlap: 2 providers hold both BCBA and RBT credentials and are included in each count. The dual-credential group is small, but it may reflect career progression from technician work toward behavior-analytic supervision. The much larger RBT cohort indicates substantial direct-care capacity relative to the listed BCBA supervision pool. That imbalance can constrain caseload growth if supervisory capacity does not expand alongside technician hiring. The data also reports 59 providers with multiple taxonomies, so credential and taxonomy categories overlap and must not be treated as mutually exclusive workforce shares.

Workforce Demographics

Women account for 163 providers, or 68% of the reported workforce. Men account for 42 providers, or 18%, while nonbinary providers account for 34, or 14%. No notable organizations appearing multiple times were identified in the supplied data. Sacramento leads the listed cities with 42 providers, followed by Fresno with 38, Modesto with 32, Riverbank with 28 and Stockton with 21. The concentration of RBTs alongside comparatively limited BCBA representation suggests that Central Valley ABA access may increasingly depend on expanding supervisory capacity and retaining BCBAs as the direct-care workforce grows.
