Orange County recorded 163 providers in the latest CMS NPI Registry weekly update, representing 2% of the national weekly total. The registry includes 107 new providers this week, with 109 new providers recorded this year. The concentration positions Orange County as a significant regional behavioral health hub, although NPI registrations reflect provider records rather than a direct measure of active service capacity.
ABA Credential Mix
The credential mix is heavily weighted toward direct-care staff: 99 RBTs compared with 6 BCBAs. No providers were identified with dual BCBA and RBT credentials. Because credential and taxonomy fields can overlap, these categories should not be treated as mutually exclusive shares of the full provider count. The roughly 1:16 BCBA-to-RBT ratio points to substantial demand for supervisory capacity; a small BCBA pool may constrain caseload growth even as the RBT workforce expands. The registry also identifies 13 providers with multiple taxonomies, reinforcing that some records represent broader professional roles.
Workforce Demographics
Among individual providers, 113 are female, representing 75% of the individual workforce. The registry lists 31 male providers at 21% and 6 nonbinary providers at 4%. No notable organization appeared multiple times in the update. Orange led the county’s city counts with 41 providers, followed by Garden Grove with 19, Irvine with 17, Santa Ana with 15, and Placentia with 12.
Overall, the update suggests expanding ABA access through rapid RBT growth, while the limited BCBA count highlights a continuing need to recruit and retain supervisors.
