What we collect
Information you give us
When you request an appointment through this site, you choose what to share: who the visit is for, the reason, an optional note, your preferred office, time and provider, your name, phone number, email address, and insurance selection. The contact page’s message form takes your name, your phone number or email, and your message. The practice updates list takes your email address, and the callback form on the balloon sinuplasty page takes your name and your phone number or email. These three forms also note the page they were sent from. With each of these, the site also records the time, a shortened cryptographic fingerprint of your network address (used only to limit abusive automated submissions, and cleared after two days), and your browser type.
Searching the site sends your search words to our server to find matching pages. Search queries are processed to return results and are not stored with your identity.
How it is used
How the practice uses what you send
Appointment request information is used to contact you and arrange your visit: it is delivered to the practice’s office staff and referenced by the confirmation number you are shown. A message or a callback request goes to the office staff so they can answer you. An email address on the practice updates list is used only for occasional practice news; to leave the list, reply to any list email or call either office. None of it is used for advertising, shared with advertisers, or sold. Ever.

Medical records
This website is not your medical record
This website is a scheduling and information surface, not a medical record system, and nothing you submit here becomes part of your chart until the office enters it. The practice’s Notice of Privacy Practices, which governs your health information under federal law, is available from either office. For records requests, call the office that holds your chart.
Children
Requests for children come from adults
This site is not directed at children. Appointment requests for a child are made by a parent or guardian, and the information is handled exactly as described above.
Your choices

To review, correct, or ask us to delete information you submitted through this site, call either office and reference your confirmation number if you have it. See also Your Privacy Choices and the cookie policy.
