Best dental practice
Our teen daughter had an infection. They got her in and had to stay late to work on her. Always appreciate that they give treatment options and never force anything but give their caring advice. She needed novocaine and a procedure done. She had never even had a cavity before but Dr. DeHart was very careful and considerate and did an excellent job as usual. Honestly, this is the best dental practice I have used on every level from the front office to the dentists and all the other professional staff. Very thankful to have been referred to them several years ago.

Love this practice
Back for a cleaning and always happy with the excellent service and professional atmosphere while feeling like a valued part of the family. I appreciate that they respect my decision to decline fluoride for my daughter. Never feel pressured to have services we don't feel comfortable with. Very thankful for that.

Best dental practice
This is the best dental practice we have ever used. Everyone and everything is so excellent and professional. Our daughter had a cleaning and has a chipped tooth and Dr. Ernie did a great job explaining the different options. We always feel well taken care of.

Feels Like Home
This may be an odd way to describe a dentist, it’s it’s true. The futuristic office and ultra-friendly staff all make it a pleasant experience. They have moved to a new office and have upgraded the building, technology, and tools and even have added Netflix for entertainment. The hygienists, doctors, and receptionists all are super friendly and helpful. I also appreciated the Keurig coffee while waiting. Huge upgrade from the last building. Treat you like a human.... almost like Southern hospitality or what I’m used to in northwest Iowa.
