Trusted, Proven

By far the best dental experience I have ever had. I had a lot of work done here - extraction, implant, cleaning, fillings etc. and for someone who is usually afraid of the dentist they made me comfortable throughout the year. I recommended this place to a close friend and he had the same experience. I had to move out of state otherwise this would be my dental office for life. I’m very lucky to have come across the people at this office. If I could give this place 100 stars I would.

This practice is extremely good. The periodontist was very informative about the work she was doing, and the upcoming dental work that needs to be completed. The front desk staff, as well as the individual handling the finances, are courteous, knowledgeable and informative. I am appreciative that I found this practice.
