A Loudoun couple who allegedly ran a dental office in the basement of their Leesburg home have been charged with practicing dentistry without a license, officials said.

Nelson A. Castro-Diaz, 47, and Matilde A. Lindarte-Vargas, 35, had a full-service office in their home in the 1200 block of Tennessee Drive that included a dental chair, waiting room and a receptionist desk, according to Loudoun Sheriff’s officials. Authorities said the office catered to the Latino community.

The couple told investigators they had worked as dentists in their native country, according to sheriff’s spokesman Kraig Troxell. Troxell said he didn’t know what country the couple were from.

Castro-Diaz and Lindarte-Vargas were released on their own recognizance, authorities said.
