With Dr. Mary Di Lisio I don't get anxious at all. Everyone there is so nice and puts your comfort level first.
Dr Di lisio is wonderful. She doesn’t push you to have unnecessary procedures like many others will do! Her staff is warm and welcoming! Highly recommend!!!
My boys 6 and 10 had our first visits with Dr. Di Lisio And her team. We all had a great experience. The Dr and her team were nice and explained dental health in ways my boys easily understood.
Dr. Dilisio has expertly guided us through each situation with thoughtful recommendations and truly amazing results. Dental issues can be stressful and overwhelming, but she has a calm, clear way of walking you through everything—and it makes a big difference.
We also absolutely love the hygienists! We've actually followed [our hygienist] to three different offices over the years. She's wonderful—and so is the entire hygiene team. They’re kind, gentle, and fantastic with kids.
I was extremely nervous as I’ve not been to the dentist in years, but it went really well & I’m happy with choosing this office for my dental care.
I never thought I’d give a dentist a five-star review but it was honestly wonderful as a new patient! They have an INCREDIBLE dental hygenist who eased my fears and was so empowering and understanding.
Everyone is very professional, [our office manager] the office coordinator is exceptional!!! The doctor and staff are friendly & genuine. They never push for extra services, they give you the facts and answer all of your questions professionally.
Talked to Dr Dilisio about getting Invisalign because I hated the gap in my teeth. She gave me the run down, expectations, length, just all the information I needed to know. My teeth look absolutely amazing she was very transparent and listened to my expectations!!!
The office got me in right away even though they were booked for weeks out, I was in so much pain-so thankful I got in when I did! Thanks Luminous Smiles!
I like that she did not rush to fill an area, but will watch it and recheck again with next cleaning. I am very pleased with my experience with this new dentist.
I wasn't happy with my bridge but Dr. Di Lisio made it right she always listens to you and your concerns and I really appreciate that.
Now the new dentist is Dr. Mary and she is amazing. I am no longer afraid to go to the dentist.
Great dental office doesn’t try to sell you things you don’t need very straightforward not pushy at all. Great staff very personable, kind and great to chat with very fun but laid back environment.
Hands down-this is the best dental office! My family has been coming here for close to 15yrs now. The office is staffed with the most caring people that we pretty much call family these days.
Everyone was so very sweet and kind making you feel very comfortable in a situation that is normally not. Most definitely my forever dentist office!
Once again, a stress free, pain free and informative teeth cleaning by [our hygienist]!
Everyone is so friendly and professional. Very clean office, always decorated for each holiday.
