South Bay LA recorded 116 providers in the latest CMS NPI registry weekly update, representing 1% of the national weekly total. The registry lists 101 new providers this week and 103 new providers this year. Records include 112 individuals and four organizations. The concentration signals substantial provider-registration activity in the region, although NPI records do not confirm whether a provider is actively practicing, accepting patients, staffing a specific site or offering ABA services.
ABA Credential Mix
The registry identifies six BCBA providers and 99 RBT providers. These categories overlap: one provider holds both BCBA and RBT credentials and is included in both counts. That dual credential can reflect progression from direct-care work into behavior-analytic supervision, though the registry does not establish a current supervisory role. The large RBT-to-BCBA imbalance points to a workforce weighted toward direct services rather than clinical oversight. For ABA operators, that pattern can make BCBA recruitment, supervision capacity and caseload management central constraints on expansion. Seven providers have multiple taxonomies, so credential and taxonomy categories are not mutually exclusive and should not be added together.
Workforce Demographics
Women account for 94 providers, or 84% of the reported workforce. Men account for 15 providers, or 13%, while three providers, or 3%, are nonbinary. No organization appears multiple times among the notable organizations. El Segundo is the dominant city with 83 providers, followed by Torrance with 15 and Gardena with 11. Hermosa Beach has two, while Lawndale, Carson, Redondo Beach, Lomita and Hawthorne each have one. Overall, the update suggests strong ABA workforce activity in South Bay LA, but access growth will depend on expanding BCBA supervision alongside its much larger RBT base.
