    I have gone to Dr. OGrady since he came to Danville. A very cautious Dr. Never recommends anything that you do not need, as some dentists do. Very calm and caring about you and your family. Wonderful for the entire family. Good with children.

    Dr. I always give an honest assessment of your conditions and allows you to determine what you're doing going forward. He never tries to sell you anything. Great guy and very thourough. Highly recommend

    I went to Dr. O'Grady for a "second opinion" based on the high recommendations I saw on Yelp. I was thrilled to get the finest service from the "front office" and from the Doctor himself. His beside manner, ability to explain and calming demeanor make visiting the dentist as pleasurable as possible. Looking forward to making him my full time dentist!
