We know you have many choices when choosing a Dentist in Spring Hill, FL so we have made requesting an appointment a simple process via our Web site. If, for any reason you cannot keep a scheduled appointment, or will be delayed, please call us as soon as possible.


We will gladly file your insurance claims as a courtesy to you. It is your responsibility to know your coverage and policy. Your insurance coverage is an agreement between you and your insurer. We will request a pre-determination from your insurance company to ascertain whether they provide coverage for certain procedures and also to finalize the amounts of coverage. We do require payment of the estimated co-payment and deductible at the time of service. After your dental plan processes your claim, you will be responsible for any remaining balance. If your dental plan has not paid your account in full within 45 days, the balance must be paid once you receive your billing statement. Please be aware that some, and perhaps all of the services provided may be non covered services and may not be considered reasonable and customary under your dental plan. Our practice is committed to providing excellent patient care and our charges are usual and customary for our area.
