The Bay Area recorded 274 providers in the latest CMS NPI registry weekly update, representing 3% of the national weekly total. The registry lists 260 individuals and 14 organizations, showing that the area’s activity is driven primarily by individual practitioners rather than provider entities. The concentration signals a substantial behavioral health workforce and a strong pipeline of NPI registrations, although registry records do not confirm whether providers are actively practicing, accepting patients, staffing a site or offering ABA services.

ABA Credential Mix

The update identifies 13 BCBA providers and 111 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 direct-care work toward behavior-analytic supervision. The much larger RBT cohort points to substantial technician capacity relative to the BCBA pool, potentially creating supervisory bottlenecks as clinics expand caseloads. Credential counts are not mutually exclusive with the registry’s other classifications: 63 providers have multiple taxonomies, so categories should not be added together as separate workforce shares.

Workforce Demographics

Women account for 169 providers, or 65% of the reported workforce. Men account for 62 providers, or 24%, while 29 providers are nonbinary, or 11%. Catholic Charities of Santa Clara County and Bonita House, Inc. each appear twice in the organization records. Concord is the leading city with 40 providers, followed by San Francisco with 25, Oakland and San Jose with 21 each, and Hayward with 17. The Bay Area’s large RBT base alongside its smaller BCBA cohort suggests that improving ABA access will depend not only on recruiting technicians, but also on expanding supervisory capacity across the region.
