What Our Patients Say

  • 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!

  • 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.

  • 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

  • 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. Update: I had my first cleaning last Thursday (3/23/23). The dental hygienist Mary Jo was the sweetest, and thorough with my cleaning. We made good conversation while she assessed the health of my gums and teeth. She didn't sugarcoat anything, which I appreciated. She was also optimistic about the overall health of my gums and teeth, which put me at ease. Dr. Mulligan came in to do her own evaluation. She seemed stressed so I was amazed at how professionally she conducted herself. She handles stress way better than some of the dentists I've been to. She gave me some tips on how to better floss while not hurting my gums. She too was satisfied with the state of my gums and teeth. Thanks you two! I feel like I'm in good hands while I'm at Grand Ave. Dental.

  • 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!
