Dr. Dana is a Delta Dental preferred provider. We are committed to helping you maximize your insurance benefits from other insurance plans as well. Because insurance policies vary, we can only estimate your coverage in good faith but cannot guarantee coverage due to the complexities of insurance contracts. Your estimated patient portion must be paid at the time of service. As a service to our patients, we will bill insurance companies for services. If you have any questions, our courteous staff is always available to answer them..
