Many dental practices insist on having clients pay upfront and deal with insurance claims themselves.
Here, we bill your insurance directly, saving you time.

We accept payment from most other dental insurance companies and process our claims electronically on the same day as treatment is rendered.

You should contact your dental insurance provider for details of your plan, however, we will be happy to help you find out your personal coverage and explain the terms of your plan . Be sure to come to your appointment with a current insurance card, and the holder's identification information. We will do our best to help make insurance processing flow as easily as possible!

Please note: insurance payments vary from plan to plan, and you are responsible for balances remaining after their payment. For treatment plans involving several appointments, we recommend that we process a pre-treatment estimate so that you can know your financial responsibility prior to treatment starting.

  • We accept VISA, MasterCard and American Express, as well as personal checks and cash.
  • Payment is expected on the day of treatment, unless we are processing your insurance claim.
  • Any balances remaining after insurance payments are due within 30 days of being billed.
