Patients in the Bronx have learned that the dentist who performed their procedures — including botched procedures — was actually not a doctor but an office manager. Valbona Yzeiraj, 45, worked as an office manager at Dr. Jeffrey Schoengold’s office and claimed that she was a trained professional from her native Albania. However, even if true, she is not licensed to practice medicine in the U.S. but performed procedures on patients, including a root canal that left a patient with an infection and another with “persistent pain” two years after the procedure.
