A high quality, fully equipped and beautiful practice. A genuinely happy, kind and professional team.
I flew from New York after hearing high praise. I had not gone to a dentist in four years. I work hard, I had not found the time to go. And then there was the dread. I am from a generation where you fear going to the dentist. But after hearing the praise and reviewing the website, I found I was actually looking forward to going. I booked two appointments, one day after the other. I anticipated I would need them. I had two old amalgam fillings which had crumbled, I felt sharp edges and I wanted those fixed. The first appointment was for cleaning, for the collating of information, and for the dentist to have a look see and decide best steps forward. The second was to address the teeth I felt cutting at my tongue. I was not surprised I needed a third appointment, and have booked to return in two weeks. And yes, I am looking forward to returning. And I will return twice a year thereafter for cleaning. I don’t think I will ever want to go anywhere else.

Thoroughly professional and friendly dentists and staff
Dr. Ernie did an amazing job putting a filling on the outside front of one of my teeth. I can't even tell it's there since it is so perfectly matched up with the surface of my tooth!

Best dental practice
Our teen daughter had an infection. They got her in and had to stay late to work on her. Always appreciate that they give treatment options and never force anything but give their caring advice. She needed novocaine and a procedure done. She had never even had a cavity before but Dr. DeHart was very careful and considerate and did an excellent job as usual. Honestly, this is the best dental practice I have used on every level from the front office to the dentists and all the other professional staff. Very thankful to have been referred to them several years ago.
