Patient Review By Jacqueline V

I am so happy that I changed to DiNinno Family Dental. I was looking for a new dental practice and they are very close to where I live. Everyone was so helpful. The office and examining rooms were immaculate!! Staff was very friendly both on the phone to schedule my first appointment and when I arrived. I felt very comfortable there right away. I had to have a procedure that I wasn't looking forward to BUT Dr. DiNinno made me feel like "everything would be ok!! Jackie V

Patient Review By Theresa S

I wish I could give Dr. DiNinno and his wonderful staff 10 stars. I had to have extensive work done on a majority of my teeth, caps and bridge, and I am so pleased and happy with my results. I feel like a new person. From beginning to end, Dr. DiNinno explained the entire process to me, and we made decisions together in a most collaborative way. In summary, he is the best dentist I have ever had in my 72 years. His staff from the front desk to the hygienist to his assistants are friendly, capable and do a great job. I highly recommend him. You will not be disappointed, and I look forward to continuing to get my dental care from him.

Patient Review By Nicole G

One of my top front teeth was in need of a crown. My teeth have quite a bit of variation in color, so I was a bit worried about making it look authentic. Dr. DiNinno did an excellent job matching the varied color and tone of my tooth. It's definitely hard to tell which tooth is the crown! In addition, Dr. DiNinno and Maggie were always friendly, helpful, and considerate when working with me.

Patient Review By Steven S

I can trust them! The shoot straight with me. They welcomed me to stay in the room with my child and brought in a comfy chair, all the while teaching me what they were doing and answering my many questions. They made me and my child feel extremely at ease and at home. Thanks!! We love you.
