DOC has treated my daughter terribly. We simply tried to reschedule an appointment, due to the fact that she stayed late after school in tutoring, and a receptionist named Stefanie literally told her that 'she is not able to reschedule'. Later, after we called back, and demanded to know what dentist was refusing to reschedule, the connection was "lost". Eventually, she back-pedaled and called back and left a voicemail stating she had scheduled an appointment on my daughters' behalf. We are disgusted by the sub-par customer service, and feel very unappreciated. Looking for other dentists as we speak.
