The DC/Baltimore Corridor recorded 244 providers in the latest CMS NPI registry weekly update, representing 2% of the national weekly total. The registry added 137 new providers this week and 163 new providers this year. With 214 individuals and 30 organizations listed, the corridor’s activity signals a substantial behavioral health hub spanning DC, Maryland and Virginia.

ABA Credential Mix

The registry identifies 17 BCBA providers and 104 RBT providers. These categories overlap: 4 dual-credentialed providers hold both BCBA and RBT credentials and are counted in each category, so the figures are not mutually exclusive. The resulting BCBA-to-RBT relationship is roughly 1:6, indicating a large direct-care workforce relative to the listed supervisory pool. That structure can support broad service delivery, but it also places pressure on BCBAs’ supervision capacity and does not establish active caseloads or appointment availability. The registry also reports 44 providers with multiple taxonomies, creating additional overlap across professional classifications.

Workforce Demographics

Women account for 158 providers, or 74% of the reported workforce. Men account for 31 providers, or 14%, while 25 nonbinary providers represent 12%. The update lists Sisters in Action LLC and Pomelo PC twice each, showing limited repeated-organization activity rather than clear dominance by a single employer. Baltimore leads the corridor’s city counts with 49 providers, followed by Washington with 41, Columbia with 15, Silver Spring with 12 and Rockville with 11. The corridor’s expanding RBT base suggests growing ABA reach, while the smaller BCBA pool highlights an ongoing need for supervisory workforce development.
