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

  • Drs. Amble and Mulligan + staff are like family and this means everything to a person that fears anything dental related. I came to Amble after receiving a referral from a client. From this I was given the gift of comfortable, accommodating and gentle care for myself and my children. Dr Mulligan and Amble genuinely take the time to know you personally and your concerns, which diminishes fear or aversions. My children are eager to go to their appointments, as am I.

  • 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.

  • Dr Amble and Grand Avenue Dental staff is just amazing. Robin is the glue for me. They are so very on top of scheduling and insurance. We love the hygienist and always enjoy our time there. I have been going there for 20 years, my daughter’s 1st dentist and she feels so comfortable. We would recommend them to anyone. Great Location, charming and stylish office. Q & Bella

  • I had my teeth cleaned and an exam. I could have fallen asleep during the cleaning it felt like a gum massage. The exam was thoughtful, thorough and clearly communicated. This will be my dentist office and I would recommend this office to friends and family

  • 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!
