I just had a cleaning with Jacqueline and it was great experience, she was fast, through, kind and personable. Highly recommend her.
DR Harris himself is also very good. My entire family has switched to his practice. Definitely would return.

I have been avoiding the dentist for about 7yrs now due to a horrible experience elsewhere. Was referred here by a colleague and decided it was finally time to get back on track. I scheduled/had my consultation and Mark was very kind and patient with addresses my concerns (mainly just financial concerns since that was the issue elsewhere previously) he was very thorough and helpful with explaining what i needed done and how we should go about it. Scheduled my deep cleaning and was assisted by Jacqueline, she was very kind and gave me plenty of education and tips to improve my dental health. Everything

Always the best service when we get our check-ups. Both my husband and me have been patients of Dr Harris for years. Great staff and can usually accommodate us when we need emergency visits.

I’ve been going to Dr Harris for about a year and I love them.. I hate going to the dentist.. it gives me anxiety.. They don’t try to get money out of you.. Every other Dental office I’ve had in the past was all about money, I would go in for a cleaning and they say I needed $$$$ of dollars of work on my teeth.. Dr Harris office is NOT like other Dental office.. They will tell you what you need to get done and it’s not $$$$ and they are not pushy about it.. Assistance Janine and Jacquelyn are so sweet, professional and do an amazing job. Receptionist always helpful and kind. Dr Harris you
