Dear Patient:

We hope this letter finds you and your family in good health. Our community has been through a lot in the last few months. We are now fully open and here to serve your dental needs. While many things have changed, one thing has remained the same, and that is our sincere commitment to your safety and well-being.

Infection control has always been a top priority for our practice, and hopefully you have seen this during your visits to our office. Our infection control processes are made so that when you receive care, it’s both safe and comfortable. We want to tell you about some old and new procedures we are implementing post pandemic closure.

Our office follows infection control recommendations made by the American Dental Association® (ADA), the U.S. Centers for Disease Control and Prevention (CDC), and the Occupational Safety and Health Administration (OSHA). We follow the activities of these agencies very closely so that we are up to date on any new ruling or guidance that may be issued.

You may see some changes when it is time for your next appointment. We made these changes to help protect our patients and staff. For example:

  • We have just implemented a new patient portal. Please register and complete the forms sent by email or text. New patients, click here. 

                                                    Existing patients, click here.

  • When you arrive, we ask that you wear a mask at this time. Please only bring personal belongings needed for the appointment.
  • There is a sanitation station in the reception room. We no longer offer magazines and children’s toys since those items are difficult to disinfect.
  • Please remember that as circumstances change, we will do our best to keep you safe.

We look forward to seeing all of you again and are happy to answer any questions you may have about the steps we take to keep you and every patient safe in our practice. If you have a dental emergency, please call the office so that we can make determinations within the allowed guidelines. Keep posted to our website,, for further information as it becomes available to us.

Thank you for being our patient. You have all been so kind and understanding in these very trying times for a small business, and we want you to know we appreciate all of the love and support you have shown us. We value your trust and loyalty and look forward to welcoming back our patients, neighbors and friends.
