For several years, Krista Szewczyk allegedly drilled, pulled teeth and performed surgeries, despite having no training.
Szewczyk is facing several felony charges, including practicing without a license.
She refused to answer questions from a reporter from the ABC station in Atlanta.
Szewczyk denies the charges and says she's a victim of a personal vendetta by the district attorney's office.
Prosecutors say she's been practicing for at least seven years.
