  • Dr. Kwitnicki is a highly trained, knowledgable dentist with many years of experience. He is all about the patient and has a superb “bedside manner.” Case in point: as a youngster, my son had a very bad experience with a different dentist. When I told him that I would be taking him to his dental appointment in a few days he asked, “Is Dr. Kwitnicki my dentist?” When I answered yes he sighed with relief and said, “Oh, thank GOD!”

  • All of my life I have been terrified of dental work, and I am not young. I have recently had the need for extensive dental work, and Dr. Kwitnicki was recommended. I reluctantly scheduled an appointment, because I had no choice but to have the work done. From the moment I entered the office and was greeted by Franny, all my fear disappeared. Franny was immediately welcoming and comforting. Once I met Dr. Kwitnicki, he had my complete trust and confidence. I came to find out they were well placed. Not only is he a superior dentist, he is one of the kindest people I have ever encountered. It is without any reservation I recommend Dr. Kwitnicki for all families, especially those who are frightened of dentistry. He, Franny, and Tatiana make the experience very positive. And on top of all that, I am proud of my beautiful smile! Thank you with all my heart!
