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.

What Our Patients Say

  • Dr. Amble was my dentist for many years. 2 years ago we moved to AZ & needed to find a new dentist. This past January we moved back to MN & I was so happy to once again be able to resume having Dr. Amble as my dentist. He is the best representation of "gentle dentistry" I've ever known. He & his staff are fabulous!

  • I so appreciate the personalized care that Dr. Mulligan and each of the staff at Grand Avenue Dental provided both my husband and myself. Dr. Mulligan also provided great patient education in an accessible way that helped me learn more about my teeth and dental hygiene in general. I feel lucky to have found this dental clinic.

  • My first, of what will be numerous, visit was a great experience. Grand Ave. Dental did a swell job of welcoming me to their practice, beginning with the receptionist to closing out with the dental assistant, Stephanie. Dr. Mulligan was professional, attentive, competent, and even displayed a nerdy side. She took out the problem tooth that had given me so much pain for a week, with flawless expertise, then referred me to an oral surgeon that will extract the remaining wisdom teeth. Thank you for your care! I'm looking forward to my regular cleanings.

  • Excellent experience. Professional, friendly staff. They were able to schedule me quickly to deal with a painful cracked tooth. Dr. Mulligan clearly explained the problem and options. The result - I am pain free! Thanks to the team!
