What Our Patients Say

  • Dr. Mulligan is awesome! The staff is as well. Back in the early aughts Dr. Amble changed what dentistry means for me after so many poor experiences. Would recommend to anyone needing basic or advanced dental care.

  • The team here is welcoming and kind. I recently established care with Dr. Mulligan and I am very glad I did. Dr Mulligan spent ample time discussing treatment recommendations and addressed all of my dental concerns. Dr Mulligan also encouraged me to be apart of my treatment planning and welcomed my feedback. Thank you for a great service at Grand Avenue Dental!

  • 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

  • The staff was very friendly. I really appreciated how Dr. Mulligan explained everything beyond what has ever been communicated with me in the past at other Dentists’ Offices. She’s very knowledgeable and was happy to pass on everything she knew.
