I agree to be responsible for payment of all services rendered to me or to my dependents. I understand that payment is due at the time of service unless other arrangements have been made. If payments are not made on the agreed dates, I understand that a $15 late fee may be added to my account. I also agree to notify Mannheim Dental of any change of address, phone number, or insurance within 30 days of such change. If I fail to meet these requirements, I authorize the use of all appropriate means, including credit history records, to locate my new address for collection purposes.
