Why our patients smile

“I had not been to the dentist in over 10 years because I don’t like the dentists I have been to in the past.  My first visit with Dr. Colleran’s office was overall a great experience for me.  All the staff  was friendly, worked great together and they are very knowledgeable and passionate about what they do which was refreshing.  They were not pushy but made recommendations of future work needed with no pressure.  I will continue going there but routinely as I should.  I highly recommend his office! :)” – Valerie
