The DC/Baltimore Corridor recorded 482 providers in the latest CMS NPI registry weekly update, representing 5% of the national weekly total. The registry lists 354 new providers this week and 374 new providers this year. Records include 441 individuals and 41 organizations, indicating activity from both clinicians and provider entities across DC, Maryland and Virginia. That concentration makes the corridor a significant behavioral health workforce market, although NPI records do not confirm active practice, patient access, staffing levels or ABA service delivery.

ABA Credential Mix

The registry identifies 9 BCBA providers and 296 RBT providers. These credential categories should not be treated as mutually exclusive, although the data reports no dual BCBA-RBT providers. The gap between the groups points to a workforce weighted heavily toward direct-care technicians, while the smaller BCBA pool represents the available supervisory layer for behavior-analytic services. The data also reports 55 providers with multiple taxonomies, so taxonomy counts can overlap with credential counts and should not be added as separate workforce shares. Other credentials include counselors, social workers, speech-language pathologists and psychologists, reflecting a broader behavioral health ecosystem around ABA.

Workforce Demographics

Women account for 328 providers, or 74% of the reported workforce. Men account for 70 providers, or 16%, while 43 providers, or 10%, are listed as nonbinary. Sisters in Action LLC appears three times; Randall Therapeutic Services LLC appears twice. Rockville leads the area with 172 providers, followed by Washington with 61, Baltimore with 58, Columbia with 20 and Pikesville with 16. The update suggests strong workforce expansion, but ABA access will depend on converting the large RBT base into services supported by sufficient BCBA supervision.
