We have updated our Covid protocols. Please click here if you would like to see our new standards.

Our goal at GAD is to keep all patients safe, including those that are immune compromised and at risk for communicable diseases. Therefore we continue to ask patients or staff members that are unwell to stay home. While our public areas are now mask optional for patients and staff we support patients wearing masks and will make sure our face coverings are secured prior to asking patients to remove their own masks for their appointments.Additionally we adhere to CDC and BOD (Board of Dentistry) guidelines and are prepared to don higher level masks if warranted by increasing COVID transmission rates. We are minimally wearing level 3 surgical masks and changing them between aerosolized procedures or if they are soiled or damaged. We follow Universal Precautions which includes PPE such as masks, eyewear, gloves, and coats and we continue to adhere to strict sterilization protocols. We continue to run HEPA filters in each operatory.

  • I highly recommend Grand Avenue Dental. Dr. Mulligan thoroughly reviewed the status of my dental health and alerted me to potential treatments should my old fillings compromise tooth stability. She took the time to answer my questions and offered helpful suggestions. Also, from the moment I arrived to the end of my appointment, each member of her team made my care their top priority. I’m so pleased I found my new dentist!
