Orange County recorded 171 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The registry lists 98 new providers this week, including 102 new providers this year. With 162 individuals and 9 organizations, the county’s activity signals a substantial and expanding behavioral health market, although NPI registrations do not measure active caseloads, employment status or appointment availability.

ABA Credential Mix

The update identifies 6 BCBAs and 72 RBTs. These categories overlap: 2 providers hold both BCBA and RBT credentials and are counted in each total. Credential and taxonomy categories are not mutually exclusive. The registry also reports professionals with credentials including LCSW, APCC, LMFT and speech-language credentials, while 29 providers have multiple taxonomies. The much larger RBT group indicates a strong direct-care workforce, but the smaller BCBA pool points to limited supervisory capacity. In ABA operations, that imbalance can make BCBA recruitment, caseload management and efficient RBT deployment central to growth.

Workforce Demographics

Women account for 128 providers, or 79% of the reported workforce. Men account for 20 providers, or 12%, and nonbinary providers account for 14 providers, or 9%. Orange County Association for Mental Health appears multiple times, with 3 registrations across Orange County cities; repeated organizational records may represent separate NPIs or service classifications rather than distinct providers. The leading cities are Orange with 25 providers, Santa Ana with 22 providers, Irvine with 21 providers, Anaheim with 18 providers and Costa Mesa with 12 providers. Overall, the update suggests broadening ABA access and a growing RBT pipeline, with supervisory capacity remaining the workforce constraint.
