This is an amazing dental practice. Dr Sharp is wonderful and I am so glad to find her at this practice. From the first call to the office to the time I walked out of my first visit everyone on the team was kind, enthusiastic, and pleasant. I was so impressed Dr. Claustro herself checked on me several times while I was in treatment. The team took into consideration my anxiety around the dental visit and went above and beyond to make sure I left feeling better then I arrived. This is a wonderful office I would recommend to anyone but especially to those of us who are nervous about dental visits.

What an amazing dental experience. While I am not afraid to go to the dentist 🦷 I have my challenges… The ladies were absolutely fabulous, kind and very caring. From Rebecca who greeted me, Brook the hygienist and both Dr Claustro and Dr Sharp it was clear I was in good hands. This was my first visit to the practice so I was scratching my head at the 90 minute appointment. It was fabulous as they took the time to understand me and my needs as well as showing me how/where I could improve my dental hygiene. Brook was absolutely superb. It was a real first class experience.
