Probably the most positive dental experience I have ever had, even though my teeth weren’t in the best shape haha! I had put off going to the dentist for a couple years because of a silly fear of the dentist. The whole time I was in my appointment I felt so calm, and I attribute that to the care of the hygienist (I can’t remember her name!) She was so professional, knowledgeable, and let me know everything she was doing before she did anything which made me comfortable knowing what to expect. Dr. Winn was very nice, talkative and personable. She gave me no shame about the state of my teeth, and that meant a lot to me. The front desk woman was also so kind and outgoing! I have to go back for some work and I am not nervous at all, I feel so safe and well taken care of there!

Charming waiting area exudes relaxed friendliness compared to other waiting areas I have been in which exude cheapness and practicality. Another thing that has struck me is that the staff seems to be friendly and responsible grownups, not what one so often sees these days where young people on staff seem to be over-stressed and underpaid as well as being under trained. A closing plus is ample parking.

Another excellent experience!! Ran late for my appointment unexpectedly. Monica took me in quickly finished my cleaning in the shorter time frame than expected, she’s always pleasant! Time was made for Dr. Winn to come in check everything over at the end of the appt., ensure a plan for my next appt. and connected face to face to discuss. Greeted with great customer service skills by Heidi at the front desk when you arrive and leave. 5 stars hands down!
