  •   The Hygienist is very professional and friendly. Just had my first visit and Dr. Marengi was excellent. One of my caps fell of during the cleaning and he did not bat and eye. He just prepared the area and reattached it and amazingly did not add any fee's. Definitely would highly recommend him.

  •   My child had a chipped tooth we were hoping could be filed down quickly, Instead it had to be capped. It was still done quickly and we were in and out with a job well done. Thank you

  •   First of all, the environment of the office makes you feel at home. There are not many dental office that you can go to and have that comfort. Dr. Marengi invests his time with his patients and truly listens to them; explaining the different options and why one may be better than the other. He allows someone who does not understand the field be comfortable with their decisions. Dr Marengi is an outstanding, friendly, ethical and comforting doctor. My smile is extremely important to me and I know that in his hands, I will have a beautiful smile to enjoy for a very long time. Highly recommended!!! Deserves more than 5 stars!!
