Orange County recorded 128 providers in the latest CMS NPI registry weekly update, representing 1% of the national weekly total. The registry lists 79 providers new this week and 94 providers new this year, including 119 individuals and 9 organizations. That concentration signals substantial provider activity, though an NPI listing does not confirm active practice, patient availability or ABA service delivery.
ABA Credential Mix
The registry identifies 1 BCBA and 81 RBTs, with no dual BCBA-and-RBT credentials reported. These credential categories can overlap in general, but the reported dual-credential count is zero; the counts should not be interpreted as complete, mutually exclusive workforce shares. The marked difference suggests many more listed technicians than board-certified supervisors. Because BCBAs supervise RBTs, that imbalance may limit supervision capacity if these listings reflect the active local workforce. The data also report 12 providers with multiple taxonomies, a separate measure that may overlap with credential listings.
Workforce Demographics
Women make up 87 providers (73%), men 23 providers (19%), and nonbinary providers 9 providers (8%). No notable organization appears multiple times in the supplied data. Among the listed cities, Orange leads with 16 providers, followed by Anaheim with 14 providers; Irvine, Garden Grove and Santa Ana each have 13 providers. These city counts show a spread across several county communities, not a precise measure of service locations or access.
The update points to broad technician activity but a very small listed BCBA pool, making growth in supervisory capacity an important factor for ABA access in Orange County.
