Our Policies


A broken appointment is a loss to everyone. Remember, once you have made an appointment, this time is reserved for you. Please give us at least 48 hours notice if you are unable to keep your appointment. This will allow us to accommodate the needs of other patients more readily. If we do not receive a cancellation notice within 48 hours, a cancellation fee of $25 per half-hour of scheduled time will be applied to your account.


You are responsible for all charges incurred on your account.

Dental Benefits

  • We are pleased that many of you have dental benefits and our office will assist you in obtaining the maximum benefits specified in your contract. However, your benefits are a contract between you, your employer, and a carrier. We will assist you in determining your benefits as best we can. Because plans differ from carrier to carrier and pulicy to pulicy, our office may refer you to your carrier or your employer’s benefits coordinator for assistance in understanding your plan.
  • As a courtesy to you, we will file your benefits claim and accept assignment of benefits. We ask that your estimated co-payments and deductible be paid at the time of service.
  • Balances with benefit claims outstanding more than 60 days may be reverted back to the patient.
  • Not all services are a covered benefit in all contracts. Some carriers and employers select only some services to be covered. You are responsible for payment of all services regardless of the payable benefit.

Any estimated amounts due and payable by the patient (including co-pays and deductibles) are required to be paid on or by the day the services are performed.
