South Bay LA has 360 providers in the latest CMS NPI registry weekly update, accounting for 4% of the national weekly total. That concentration marks the region as a substantial node in the registry’s behavioral health workforce, though NPI records do not establish whether providers are actively practicing, taking clients or delivering ABA services.
ABA Credential Mix
The registry lists 7 BCBAs and 338 RBTs, with no dual BCBA-and-RBT credentials reported. The counts are registry classifications, not necessarily a complete or mutually exclusive account of everyone’s credentials; six providers have multiple taxonomies. The large RBT count alongside a small BCBA count indicates a workforce weighted toward direct-care roles, with a comparatively limited listed pool for assessment, treatment planning and supervision. That imbalance makes supervisory capacity an important consideration for ABA operators.
Workforce and Geography
Women account for 223 providers (62%), men 54 (15%), and nonbinary providers 81 (23%). The data identifies no notable organization appearing multiple times. El Segundo leads the city listings with 286 providers, followed by Torrance with 53 and Gardena with 12; Redondo Beach has five and Hermosa Beach three. These figures show activity concentrated in El Segundo, but the update does not clarify where providers deliver services. The registry also includes two organizations among 360 total providers.
South Bay LA’s listings suggest broad RBT presence but a much smaller BCBA pool, making supervisor availability a key factor in whether local ABA access can keep pace with provider activity.
