The Inland Empire recorded 140 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The registry added 83 providers this week and lists 95 added this year. Records include 134 individuals and 6 organizations, signaling active provider registration across a sizable regional behavioral health market. NPI activity does not confirm that a provider is practicing, accepting patients, staffing a site or offering ABA services.
ABA Credential Mix
The update identifies 14 BCBA providers and 76 RBT providers. These categories overlap: 3 providers hold both BCBA and RBT credentials and are included in each count. The dual-credential group is notable as a marker of career progression from direct care toward behavior-analytic supervision, although the registry does not establish current duties. The much larger RBT cohort suggests substantial direct-service capacity relative to supervisory capacity, which can constrain caseload growth when BCBA availability does not expand. The registry also reports 16 providers with multiple taxonomies, so credential and taxonomy counts are not mutually exclusive and should not be combined as separate workforce shares.
Workforce Demographics
Women account for 96 providers, or 72% of the reported workforce. Men account for 25 providers, or 19%, while 13 providers are listed as nonbinary, or 10%. No notable organizations appearing multiple times were identified in the supplied data. Riverside leads the region with 26 providers, followed by Ontario with 17, San Bernardino and Temecula with 15 each, and Rancho Cucamonga with 14. The combination of strong RBT representation and a smaller BCBA pool suggests that Inland Empire ABA access may increasingly depend on expanding supervisory capacity alongside technician recruitment.
