The Inland Empire has 161 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The registry records 96 new providers this week and 108 this year; 140 are individuals and 21 are organizations. That share signals a substantial regional presence, though NPI enrollment alone does not confirm active practice, patient availability or ABA service delivery.
ABA Credential Mix
The registry lists 16 BCBA providers and 87 RBT providers, with 3 dual credentials. Dual-credential providers are included in both counts, so these figures overlap and are not mutually exclusive workforce shares. The larger RBT count points to a workforce weighted toward direct-care roles, while the smaller BCBA count suggests a comparatively limited pool for assessment, treatment planning and supervision. Dual BCBA-and-RBT credentials may reflect career progression, but do not establish current job duties. The update also reports 29 providers with multiple taxonomies, another overlapping classification.
Workforce Demographics
Women account for 103 listed providers (74%), men 23 (16%) and nonbinary providers 14 (10%). Simple Solutions Family Therapy is the only organization identified as appearing multiple times, with two records. Riverside leads the listed cities with 22 providers, followed by Ontario with 20, Victorville with 14, San Bernardino with 13, and Rancho Cucamonga with 12. With RBT records substantially outnumbering BCBA records, the update suggests a broad direct-care workforce but a smaller supervisory pool that may shape how readily ABA services can expand across the Inland Empire.
