review OG Dental

"Dr. O'Grady is the only doctor that I will let touch my teeth or my kids teeth. He is extremely polite, as well as a very thorough doctor. He listens and explains everything very well. Plus, as I have told him, he has the hands of an angel. I have had 3 teeth extractions & felt zero pain, each time I didn't even know it was over because he is so gentle. My now 7 year old went there for his 1st time at age 5, was terrified at first, but with how caring and great he is with kids, he made my son's experience like a trip to disney land, now both of my kids practically beg for their next cleaning lol! Hands down, best dentist I have ever been to."

review OG Dental

"I can honestly say that Dr. O'Grady is the first dentist I have met who I felt I could relate to on a personal level.  He is super easy to talk to and I know that he holds himself to an extremely high standard when it comes to the care he gives."

review OG Dental

"Dr. O'Grady was professional, knowledgeable, and personable. He solved the problem with my cavity, and I am currently discomfort-free (thank you!). Not only did he solve the mystery of my uncomfortable cavity without having to re-fill it, but also he squeezed me in for a same-day teeth cleaning. The hygienist was busy with another patient so he cleaned my teeth himself! I look forward to seeing Dr. O'Grady again soon."

"From taking my first step into the office to leaving, I was met with professionalism, kindness, and an all around amazing experience. The doctor and all his staff are great at keeping you included in the whole process. They are transparent about everything and are very personable. I would definitely recommend this place to anyone who wants to feel like they can 100% trust in their dentist."

review OG Dental

"Dr. O’Grady and his team are the friendliest bunch of folks... and the level of care and caring is top-notch. As a new patient, time was spent with me before the check-up to go over treatment and care options. They even dropped some knowledge on me about treatment that I feel like I should have gotten from my previous dentists but never did. Highly recommended!"

"Dr. O'Grady is a blessing to this community because he can do so many different types of dentistry well. You don't have to be referred to different offices to get your teeth taken care of. He is really caring and understanding, and actually listens to what you have going on in your life."

review OG Dental

"Dr. O’Grady and his staff were exceptional. Love seeing this new dental office in the neighborhood and really appreciate how modern the technology is and how transparent they are with you regarding your treatment options. They go above and beyond with a comfort menu as well, offering extras such as a warm neck pillow or essential oils to really relax you. So pleased to have found this wonderful establishment!"

review OG Dental

"My fiancé said it best, “You know the dentist is good if you’re still talking about it hours later. No one talks about how awesome their dentist visit was.” This office has the best amenities out of any dentist I have ever been to. Dr. O'Grady really goes out of his way to sit down, address your needs, and make you comfortable before taking care of you. The whole staff was amazing and super accommodating. They even fit me in as a walk in new patient. I just want everyone to know about this dentist’s office because they made me feel like going to the dentist isn’t scary."

"I love being able to provide solutions for people experiencing health challenges and changing the way someone feels about their smile."
