What Our Patients Are Saying

Dr. Heron is the best dentist I have ever gone to. And I’ve been to many in my 72 years. She and her staff are highly competent, up to date, professional yet friendly. They are also very respectful and genuine. While I haven’t needed laughing gas during my visits, she and her staff use actual laughs to make a normally not very pleasant experience actually fun.

Maggie F.

Very clean facility. Friendly, professional staff. I appreciate Dr. Heron taking the time to explain what we we're looking at on my x-rays. In the past I would open my mouth and cross my fingers, but today I felt involved and very informed during my comprehensive exam. The most pleasant dental experience to date!

Veronika S.

As always, Division Street Dental is very clean with up-to-date facilities. The dental hygienist is always pleasant and cheerful and very thorough in her work ethic, as is the dentist who spends time with you to make sure your questions are answered and to take care of any concerns. Their facility is very professional and everyone who works there makes sure you feel special. I highly recommend their practice.
