I had an excellent experience here. First time getting dental work done in years and years. No judgement, just encouragement.

Dr. Johnson was personable and friendly and really made me feel like I was making the right choice. Set out a treatment plan and provided multiple options and recommendations. It felt like something I could follow through with as well.

My hygienist Kendra did and excellent job talking me through the deep cleaning, and informing me of the best way to go forward with my treatment. It was enjoyable to see the before and after pictures and see all the progress I made.

I’ve seen some negative reviews on here and I think it comes down to people not wanting to own up for their own failures. I didn’t get dental work done for 22+ years and that’s my own fault. My opinion is that people don’t like to hear that they aren’t taking good enough care of their teeth and mouth and they take it out on the staff. I highly doubt it is the staff itself.

Go to the Dentist. Go to this Dentist. They will take excellent care of you.

I can’t even describe how amazing it is here at Happy Smiles! Everyone is so personable and thorough, especially Dr. Kellie! I was in shock to read these horrible reviews at first, but out of curiosity it was nothing how it was said. I can’t believe the lengths that people go to when they don’t get their way. For my family and I, all of our experiences at Happy Smiles was amazing. We will definitely keep her as our family dentist!

Bailey Tonko

Dr. Johnson and her staff are amazing! They are so friendly and give you a warm welcome when entering. Brianna (her assistant) is polite and gentle when it came to the x-rays! Once Dr.Johnson checked my x-rays and gave me the 411 , they took me into consultation where Sandy broke down everything down step by step and told me what my insurance covers and what it doesn’t. Will definitely be coming back!!

I can’t be any more pleased with the service that I received at Happy Smiles. I was traveling with family but had some issues with a filling and was referred there. The staff is great and highly professional. Kellie does a great work and is a perfectionist at what she does. I can appreciate the extra attention to detail and going above and beyond to make me comfortable in a new setting. Thank you Happy Smiles!
