Dr Davis and his team are the best! He explains everything he’s doing, answers questions and makes every visit enjoyable. I don’t normally like dentist appointments but Dr Davis has changed my mind!

I’ve had a cleaning and filling of 2 small cavities (without anesthesia!) and both were fantastic experiences. I’ve learned that with services, you want the person who does a good job first and foremost because they care about their craft. Dr. Davis is one such person. He is a great dentist who does a great job because it matters to him. He is a kind man who truly cares about helping his patients. I highly recommend him and his team.

Visit of May 30, 2023. The staff continues to be extremely friendly, courteous, and always professional. Dr Sinclair Davis was attentive, concerned and thorough in explaining next steps. Dr. Davis has been my dentist for many years, and I look to him for his frank opinion and recommendations for continuity of my dental care. He is always passionate about the person - not just the patient in the chair.
