People, be careful and check all invoices from the company Monarch Dental Assoc. My son visited the orthodontist twice and the first visit was only consultation, which cost about $300. The second was consultation and he provided some services, and he told that the visit was about $600. So, the total sum was $900, but they sent the invoice for $1, 200. For what they took this sum? The doctor refused to speak and advised to call to the reception, but the lady refused to explain.
