Dr. O and staff are the best! They are always patient and friendly, always ask about my family, always explain everything they're doing. Adrienne (sp?) did my cleaning and was so kind, especially since I was having sensitivity issues.

I have been a long term client of Dr. O'Donnell's practice. His staff are always professional and welcoming. I would like to recognize Adrienne (dental hygienist) for her outstanding work at both providing an excellent cleaning of my teeth as well as a follow up of what is different from prior visit to current visit. She provided great detail in her explanation and made sure she included positive feedback in recognizing my effort to take care of my teeth. Looking forward to my next cleaning.
