What Public CMS Data Show
Social Worker: NPPES taxonomy is a reported classification, not proof of board certification.
NPI first issued
2025
The year this clinician's National Provider Identifier (NPI) was issued. An NPI is a unique 10-digit ID that US health care providers use for billing.

Medicare assignment not listed
