Highly recommend Doctor Castro's office. I had a root canal, crown and 2 fillings. Process was expensive, as expected but relatively painless. The treatments I had were explained to me fully, office was clean and bobby in the front office is fantastic. Will be returning for any future work that I need.
Only very minor negative is that I found none of my appointments began on time, I waited at least 10-15 mins each time which resulted in being back to work later than expected.

Approximate cost: $3000
