The friendliest and most professional dental office I have ever dealt with. The hygienists are all great. Dr. Mortensen and Dr. Skinazi are both excellent dentists and a pleasure to deal with. Dr. Mortensen even made the removal of my wisdom teeth a simple, quick, and pain-free procedure. How many people can say that? I wouldn't dream of going anywhere else.

Excellent care and "chair-side" manner! Patty and Dr. Mortensen always insure that the experience is positive and effective. 😁 They go above and beyond what is expected!

I had bad experiences going to the dentist in the past and that made me a chicken when it came to going to the dentist. Dr. Skinazi was great with me. She understood my fears and was incredibly patient, as was her assistant Christy (sic?). All of the other staff are friendly and inviting. My visits were great and the outcomes were even better. Can't recommend them enough.

Disappointed and will not be returning. I read the review by Claude and am glad to know it's not just me! I had several fillings replaced in December and since then had an issue with another tooth. I was made feel like an inconvenience when I came back to have it checked out. Bottom line is I have gone elsewhere. This office is disorganized and the dentists are poor communicators.

Unfortunately Dr Mortensen has gotten extremely impatient and rude if you ever have to return to get anything fixed. My whole family goes there and we have all experience the same poor attitude and feeling like were wasting his time. We are all moving to other care providers.
