What to bring to your first appointment

Please bring the following documentation with you to your first appointment. If you have any questions please do not hesitate to contact our office.

  • Completed New Patient form if you have not faxed them to our office yet
  • Health insurance card
  • A list of your questions, concerns, past medical history and prior treatments
  • A copy of your XRAYS, CT scans or any other relevant medical imaging (not just the reports - please acquire the actual films or images on a disc from the radiology facility)
  • Copies of records from doctors related to your sinuses, nose, allergies and lungs

What to expect at your first appointment

When you first arrive for your visit, you will be greeted by our front office staff who will check you in. Please arrive 10 minutes prior to your appointment time to allow for check in.

During check in, we will obtain a picture for you for our records, make a copy of your insurance card and accept any co-pays. Our office staff will then verify that we have received your completed paperwork and take any scans or records that you have brought with you.

You will then be brought to one of our exam rooms by our medical staff. Your medical history and records will be reviewed including: the reason for your visit, your symptoms and prior treatment. Any scans that you have brought will be reviewed with you. If you need to have a CT scan performed, we have a low dose radiation CT scanner to obtain any required imaging on the same day as your visit.

Once your medical history has been obtained by our staff, an exam of your nose and sinuses will be performed with a nasal endoscope. Prior to your exam, you will be sprayed with medication that will decongest and numb your nasal passages. The endoscope allows your provider to look deeper into your sinuses than with traditional instruments. You will be able to view your exam at the same time.

Your visit is a time for us to get to learn about you, your condition and how best to treat you. At the end of the visit we will explain our findings and help you understand your condition and treatment options.

  • Bring your current insurance card(s).
