Testimonials

What Our Patients Say About Us

    After trying a number of dentists in the area, Dr. Sim is the only one I really would recommend. His is gentile, knowledgeable, patient and conscious of each client's situation. His office is VERY clean and the staff members are attentive and very respectful. No negative aspects to report. He makes a trip to the dentist turn into a pleasant experience!

    Miriam M.

    Very professional staff at every stage. I am glad I found someone like this in the Princeton area and recommend their services highly.

    Neil M.

    Honglan L.

    Dr. Sim has done a few treatments for me. Crown work, cavity filling, and teeth condition analysis in the last few years. He is the most trustworthy dentist in my experiences. He pays a great attention, taking time to listen and talk to his patients. He explains what needs to be done and options if any. My lower back tooth had a problem for a quite some time. He knew it has to be removed and get implant. However, he accommodated my request and tried to save the tooth. After having spent much time, he explained what he thought to be done. I listen to him because he is truthful and offer the best for his patient. I highly recommend Dr. Sim.

    If I can give Dr. Sim and his staff higher than 5 stars I would. Every time I go for my appointments, I have nothing but pleasant experience. He always takes his time explaining the procedure and I never feel rushed. It's weird to think that I no longer mind going to dentist. If you are looking for a new dentist, look further!

    Jason

    Attention to detail, Excellent Check Up and Cleaning! Dr. Sim is the most thorough and trust-worthy dentist I've been to. He doesn't rush or cut corners, trying to see as many patients as possible. He gives me the check up, tooth filling (oh, well!) and mouth guard fitting that I would want from a dental practice. My family have been going to this dentist 2x/yr for 10 years but I felt I must share a review today because he went the extra mile for me last week. My mother was visiting from another state and felt discomfort in her mouth. Dr. Sim readily agreed to see her to check for something serious -- and advised that we make an appointment for biopsy with her oral care professionals as soon as she got back to her home. He really takes care of my family!
