Roxy W.

I've been going to Dentistry by Design since 2000. Met Dr. Rash yesterday for my regular cleaning and he was absolutely wonderful. He was very friendly and warm, addressed my concerns about an old damaged filling, and explained the science behind what had happened with it.

Nyles T.

Dr. Rash & Dr. White both love their jobs which has allowed them to provide such great care effortlessly. Not only that but the techs do an awesome job when it comes to the cleans also. Everybody is friendly from the front to the back and has a smile on their face. That is just an added plus!
