The Inland Empire recorded 143 providers in the latest CMS NPI registry weekly update, representing 1% of the national weekly total. The registry added 82 new providers this week and 90 new providers this year. The area includes 140 individuals and 3 organizations, signaling substantial registration activity and continued expansion of the region’s behavioral health workforce. NPI registrations do not confirm that providers are accepting patients or actively practicing.
ABA Credential Mix
The registry identifies 9 BCBA providers and 65 RBT providers. One provider holds both BCBA and RBT credentials, so the dual-credential record is included in both credential counts; these categories are not mutually exclusive. The data also shows 24 providers with multiple taxonomies, reinforcing that credential and taxonomy totals should not be read as separate, nonoverlapping segments. The large RBT presence relative to the BCBA count points to a workforce weighted toward direct-care roles, while the smaller BCBA group indicates a more limited pool of clinicians available to supervise RBTs and lead treatment planning.
Workforce Demographics
Women account for 102 providers, or 73% of the reported workforce. Men account for 25 providers, or 18%, and nonbinary providers account for 13 providers, or 9%. No notable organizations appear multiple times in the update. Riverside is the leading city with 26 providers, followed by Temecula with 17 providers, San Bernardino with 16 providers, Ontario with 14 providers and Rancho Cucamonga with 11 providers. The update suggests growing ABA access in the Inland Empire, but supervisory capacity remains a key workforce constraint.
