I don’t usually do this but I have to say what a great experience I’ve had with Chelmsford perio! Dr. Dang is a super nice man and my appointment with Donna this week was a pleasant surprise.

BS, Methuen

First when you walk in you are greeted by the pleasant and very helpful front office staff. I have been going there for years so I have had a couple of different hygienist clean my teeth. They were top notch! Clearly knowledgeable in there job and gentle. Dr.Dang is the best..excellent dentist/periodontist. Caring and understanding. I had gum surgery and he personally called me to see how I was a couple of days later. And left his own cellphone number in case I had problems. Not many people do that today!! Office is immaculate as well. You won't be disappointed ??.
