What Our Patients Say About Us

    The staff was so kind and compassionate. Dr. Eric genuinely took the time to explain what I was experiencing and why, and made my visit really pleasant. I'm so grateful to the entire team for their patience, compassion, and grace as I am one of those very very fun patients who struggles with anxiety at the dentist.

    I have always been nervous about going to the dentist but Dr. (Eric) Johnson has been amazing about putting my nerves at ease. Telling me exactly what he is going to do before he does it and making sure it is quick and as painless as possible. I’ve also had occasion to see his father Dr. (Greg)Johnson for an emergency appointment when I had a tooth crack suddenly. He was able to get me right in and once again take great care with gentleness and ease. I can’t recommend them enough. I went from “I hate the dentist!” to “I love my dentist!”

    Their hygienists have been there for years and are all great. Drs Johnson both care about their clients.

    The staff are really great and make you feel welcome! I have bad anxiety and one of the things that makes me super anxious is dentistry. Since Kaitlyn has been cleaning my teeth, I haven't had any anxiety at all.
