Orange County has 146 providers in the latest CMS NPI registry weekly update, representing 1% of the national weekly total. The registry reports 93 new providers this week and 104 this year, including 140 individuals and six organizations. The county’s share signals a substantial local provider presence, though NPI listings alone do not confirm current practice, patient availability or delivery of ABA services.
ABA Credential Mix
The update lists 9 BCBAs and 93 RBTs, with no dual BCBA-and-RBT credentials reported. The larger RBT count indicates many more listed direct-care providers than supervisors; BCBAs oversee RBTs, so this imbalance makes supervisory capacity important to sustaining ABA services. The counts should not be treated as mutually exclusive categories: credential and taxonomy records can overlap, and 11 providers have multiple taxonomies. The data does not establish how many are actively working in ABA or how supervision is organized.
Workforce Demographics
Women account for 99 providers, or 71%; men account for 37, or 26%; and four providers are nonbinary, or 3%. No notable organization is identified as appearing multiple times in the supplied data. The leading cities are Orange, with 25 providers; Santa Ana, with 16; Irvine and Costa Mesa, with 15 each; and Garden Grove, with 14. These city counts describe provider registrations, not necessarily service locations or the distribution of available care. The registry includes six organizations overall but does not name any as a repeated notable employer.
Overall, Orange County’s listings point to a broad, geographically distributed workforce with many RBTs and a smaller BCBA pool, making supervisor availability a key consideration for ABA access.
