☆☆☆☆ 4.4 Rating

I have had more than 20 dentists in my 60 years. DC Dental Spa is among the top in my experience. The professionalism and attention to each patient is excellent. I was so impressed by Dental Spa that I had them complete the work that I needed done that very day. Excellent work.

Dental procedures cause me great anxiety and their practice offers sedation options that gave me the assurance I needed to undergo much needed procedures.
