Coronavirus Update

Dear valued patient:

In an effort to support national efforts to fight the COVID-19 pandemic, our practice is taking the following steps to assure your health and well-being and that of our community:

  1. We are following directives from the Centers for Disease Control and Prevention (CDC) as a way to limit patient and staff exposure to this virus.
  2. Your health, and the health of our dedicated staff, matters to us, so going forward we will suspend all non-emergency care until further notice.

We will contact you as soon as possible to reschedule routine appointments. If you are already scheduled for an urgent issue, we will contact you the day before your appointment to discuss your health status, health screening protocols and confirm whether the appointment should be kept. Of course, please call us right away if you have a dental emergency or need immediate care.

The safety and well-being of our patients continues to be our primary concern. We will continue to monitor the status of COVID-19 nationally and within our community and keep you up-to-date regarding our plans to reopen for business as usual.

Please be assured that the technology that we use for your treatment will continue to work and a short disruption will not negatively impact your orthodontic treatment.

I urge you to contact us if you have any questions or concerns. We can be reached by phone at 717-566-3776 or by email at and we will respond as soon as we can.

Thank you,

Dr. Barbara Spangler and The Smile Team
