  • "I would never go anywhere else....never!! The only issue that I have ever had and still do....sometimes is that one of the ladies at the desk is not friendly at all and on occasion has been very short with me on the phone. As long as I have been going....for sixty years still hurts my feelings when that happens. In years past, this was never ever an issue."
    Jeannie H.
  • "This was an "emergency" trip for a broken tooth which, as always seems to happen, happened on a weekend. They got me in quickly and too measures to ease the discomfort until I can get a full repair. I would hate to go anywhere else for my dental needs. They are simply the best."
