Dentistry with a Mission

Our Core Values

We treat our patients the same way we would our family and best friends. You’re a person before you’re a patient, and we never forget this.

Going to the dentist can be stressful for some, but we keep things light and upbeat even when it’s not easy to do so.

You’ll never talk to a team member who doesn’t know who you are. Together, we’re able to consistently deliver exceptional care and service.

We consider all of the details so you don’t have to. From our appearance to our communication to your treatment, our dedication to quality will be obvious.

Leaves of Many Colors

Reviews & Testimonials

The Fruits of Our Labor
Arlington Heights dental patient Jessy

“I decently chipped my two front teeth last week and though the office was closed, Dr. DeHart responded fast and was able to fix my teeth within hours. Everything was done very gently and all of my questions were answered thoroughly, which meant a lot to me especially in my panicked and injured state. My teeth look amazing and I have never had anything but amazing experiences here. Thank you again!!”
