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.

  • 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.

  • 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!

  • 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.
