    Dr. Rosario is the best! Truly. She cares for all her patients and goes above and beyond to make them comfortable. No one likes going to the dentist, including myself. But she puts your mind at ease. Bridges are no joke. They are very long and tedious appointments. Dr. Rosario took her time, explained every detail with options and was so gentle and encouraging the entire time. If I could give her 100 stars I would. She’s honest, trustworthy and will do whatever it takes to make you comfortable and your smile just as beautiful!

    I have been going to this place since the beginning of the year. I came to this place because my other dental office was over charging me and kept changing my dentist. I'm happy to report that this place has exceeded my expectations. The staff and dentist are all friendly and personable. They remember me, my stories and follow up with me whenever I come in. Dr. Rosario is the best and she truly cares for the patient. She understands that every one has their own budget and priorities & she follows through. I was always afraid of going to the dentist due to a few negative past experiences, But I always feel at ease whenever I am at Dr. Rosario office. The place itself is very clean and calming. It is facing a busy street, parking is in the back. You would need to walk to the front door for entrance. One of the major reasons why I love coming here is that there's only one dentist and she does not overlap her appointments.
