I was very impressed with the friendly professional service. From the receptionist to the dental tech to the financial consultant. Dr. Johnston was so kind and positive he really made me feel safe and comfortable. I drove 1 1/2 hours to get there it was well worth it. I highly recommend Johnston Dental Care!
