Veronica Black Patient

Dr O'Neil was the first doctor to ever take my dental anxiety seriously. I needed a lot of work done and hadn't been able to face it because of debilitating anxiety of needles and drills in my mouth. If it weren't for him, I'd have lost a few teeth. I'm so grateful, and wish I could keep going to him for all dental work, but I'm in another state now. Couldn't recommend more!

Lottie L Patient

Great doctor. Great chair side manner. He takes his time to explain why treatment is needed and how to avoid future dental problems. Dr O'Neil is a honest and ethical human being. His staff is exceptional. They'd definitely be a good team to work with! Keep up the great work.

A GREAT experience from beginning to end. Dr. O’Neil and his staff are knowledgeable and thorough. He addressed more than just my teeth health...he’s concerned with over all mouth health. With so many dentists out there I’m so glad I found the best!
