Orange County recorded 205 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The registry count includes 193 individuals and 12 organizations, indicating substantial behavioral health activity and reinforcing the county’s role as a major regional market for ABA and related services.

ABA Credential Mix

The registry lists 10 BCBA providers and 99 RBT providers. These categories overlap: 1 provider holds both BCBA and RBT credentials and is counted in each total. The large RBT presence points to a deep direct-care workforce, but the comparatively smaller BCBA pool may constrain supervision capacity as clinics expand. NPI records do not show whether providers are actively accepting cases, their caseloads or their employment relationships. The data also identifies 15 providers with multiple taxonomies, so credential and taxonomy categories are not mutually exclusive.

Workforce Demographics

Women account for 145 providers, or 75% of the reported workforce. Men account for 36 providers, or 19%, while 12 nonbinary providers represent 6%. No notable organization appears multiple times in the update, offering no clear indication of concentration under a single named employer. Provider activity is most concentrated in Orange, with 56 providers, followed by Fullerton with 24, Irvine with 21, Anaheim with 15 and Garden Grove with 15.

Orange County’s strong RBT base suggests continued potential for ABA access, while the smaller BCBA count highlights the need to build supervisory capacity alongside direct-care recruitment.
