I had a great experience at Dr. Donan’s office today. Dr. Donan and his entire staff were incredibly polite, professional, and made me feel comfortable throughout my appointment. I had several fillings done, and they explained everything clearly while making the procedure as smooth and painless as possible. Everyone was friendly, helpful, and genuinely cared about making sure I was comfortable. I really appreciate the excellent care I received and would highly recommend Dr. Donan and his team to anyone looking for a great dentist!

Dr Donan and his staff have been wonderful to work with ever since I had my first appointment. He is extremely professional, talented, and informative, and he creates a safe space to hold dialogues with him about the state of your dental health. I had a teeth cleaning done first, and then a little while later I began the process of having 2 crowns replaced - on the same day and without any soreness. A couple weeks later I had both new crowns attached permanently with minimal soreness again. His staff is extremely friendly and informative as well, and always make me feel at home. I went in because of his great reviews, and I'm now leaving one myself!

Love Dr Donan’s office! … never thought I would say that about a dentist but truly appreciate his skill and expertise. I have been avoiding some dental work for years and have extreme detail anxiety but have had nothing but positive experiences.

Everything was fully explained to me from treatment to payments and I felt in control of what was happening.

All of the technicians in his office are very professional and kind as well

I would highly recommend Dr Donans office to anyone.
