    Don't let the friendly staff fool you. When I started as a new patient, the patient billing…read morecoordinator was very helpful and communicated regularly. Trying every which way to find another benefit code they could use to pay for things. But all the communications stopped after tapping out my dental benefits it all stopped. I felt like just a piggy bank for them. Don't go to Dr. Nishimura if you want a dentist that listens, truly listens to your concerns. She'll patronize you and and be dismissive and do what she wants anyways despite your concerns. But it's worse than bed side manor. I stopped going after she left my teeth in worse condition than when I started. I went to two other dentists since then and both told me it would cost over $20K in braces and other dental work to fix it. I have been so bummed about dentist and afraid to go to any more. Run, don't walk, from this place. You have been warned.

    The team is amazing. Dr. Kiernan is very thorough. I was expecting just a normal dental cleaning…read morebut the office visit encompasses much more than that. He conducts an assessment and asks questions to determine the patient's overall health. He reviews my facial anatomy to determine indicators which would impact my quality of sleep. He asks if I had respiratory issues... I learned I had jaw anatomy and TMJ issues... the level of care is nothing I ever experienced and I have been on this earth for many many years. Ultimately, I was diagnosed and was given an oral appliance. This appliance alleviated my sleep issues significantly and for the first time in a decade- I was able to sleep well and breathe. Doc also gave me advice which reduced my inflammation and helped me get off allergy meds. Throughout my visits, the team has been very attentive to all my medical concerns

    worst experience with a dentist . Three times had cap placed in three times it didn't work. Avoid…read moreat all cost.

    Let me start off with that I'm incredibly happy to not be writing the first review for Dr…read more DiMattia. I've been going to Dr. DiMattia for as long as I can remember. I even make the drive from the North Shore to Lexington to continue with such a tremendous dentist. From the moment you enter you are greeted by the most lovely women working the front desk. On certain days even Dr. DiMattia's wife is working. They remember most patients by name and will inquire about family, work etc. I usually see Joan for my cleanings. She books quickly because she is awesome. She does such a thorough job but you don't feel like your teeth have been assaulted. You leave saying wow so that's what they're supposed to feel like. Again Joan has worked for Dr. DiMattia for years. Having employees that stick with a dentist I think show the character of the professional. You can tell his employees hold him with high regard and so do his patients. Dr. DiMattia is personable and most importantly honest. You're never talked into unnecessary xrays, this that or anything else. Dr. DiMattia is incredibly fair on the prices he charges too. In this day and age when a good dentist is hard to find and many people fall victim to gentle dental or other national chains it's nice to know that Dr. DiMattia takes the Hippocratic oath to heart.
