What Our Clients Say About Us

  • "As some one who was really afraid of the dentist I can say I am no longer after coming here. The front office worked well with me to make sure I was using all my insurance, always reasonably priced out of pocket cost. they were always willing to reschedule me quickly when I had stuff come up. The dental assistants are on point and very knowledgeable. They never made me feel embarrassed about my teeth. Dr. Greeding is there best! I never smiled in photos before but after he filled cavities in my front teeth all my friends though I got veneers! I’d give more stars if I could!"
    Meagan L.
  • "Very pleased with the staff and dentist, very friendly and helpful on getting my cleaning and x rays done. Been with them for a few years now and would never change dentist. I drive from Maricopa and is worth the drive."
    Xavier D
  • "Just finished my appointment here and could not be happier with my experience! Everyone from the front office, hygienist (who was ridiculously pretty😍) to Dr. Greding himself were all incredibly kind, thoughtful and personable. I’ve never had a dental experience this informative, productive and painless before. I got two cavities filled in less than 10 minutes! I‘d go back just to hang with the staff. Kidding. But not really."
