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.

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.

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!!!

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.
