Yelp Reviews

  • Great customer service. They did an extremely thorough cleaning. When asked if I wanted to do an x-ray, they were able to also tell me whether or not my insurance would fully cover it. Made me happy that they knew that information up front, so that I wouldn't get a surprise bill later. Highly recommend 🙂

  • Sunny Dental is the best overall dentist I've been to. They are courteous and their prices aren't crazy either. I'd recommend them to anyone, kids or adults. I take my 4 kids all the time and none of them have ever complained

  • Can't say enough about Dr. Castro and his staff. He motivated me to take better care of my dental hygiene and is very honest too regarding treatment options. They do a great job with my 9 year old too!
