South Bay LA has 232 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The registry reports 218 new this week and 219 new this year. That concentration points to substantial provider activity in the region, but NPI records do not confirm active practice, service availability or ABA focus.
Credential mix
The registry lists 217 RBTs and 3 BCBAs, plus 1 dual-credential provider with both BCBA and RBT credentials. These categories overlap: the dual-credential provider is counted in both credential groups, so the figures are not mutually exclusive. The pronounced difference suggests a large listed technician workforce relative to BCBA supervisory capacity. For clinics, expanding direct-care staffing without sufficient BCBA supervision can limit how much service capacity translates into treatment access. The update also reports six providers with multiple taxonomies, another reason not to treat registry categories as separate workforce shares.
Workforce and geography
Reported demographics are 145 female providers, or 63%; 18 male providers, or 8%; and 66 nonbinary providers, or 29%. The registry counts 229 individuals and three organizations, but identifies no organization appearing multiple times. El Segundo dominates the city listings with 206 providers; Torrance and Gardena each have 10. Lawndale has two, while Lomita, Carson, Hermosa Beach and Redondo Beach each have one. This concentration describes listed provider addresses, not necessarily where services are delivered. The mix also includes other behavioral health and allied-health credentials, so the regional total is not an ABA-only count.
Overall, the figures suggest a sizable, technician-heavy provider base in South Bay LA, with BCBA supervisory availability a key factor in converting registry activity into accessible ABA care.
