My wife (Yana) and I (Ted)/have been going to Sudbury Dental Smile Center for over 15 years. Our each appointment was met by Dr. Ronnie Du & her staff with utmost care, kindness, and brilliant professional services. Thanks to Dr. Du our teeth never felt better while our white straight teeth make us many years younger; much better than a facelift. Being at this office is like being among friends as Dr. Du & her staff always meet us with courtesy and a wonderful sense of humor, which make us feel good and pleasantly relaxed. The office atmosphere is clean and cozy. As for the billing: they handle it in a fair and a skilled manner to optimize the cost to us. Having this dental office available to us is a blessing, and it has been by far our best choice in this field for the past fifty years.

Where do I begin,for thirty five years I was loyal to a previous dentist until he retired.Now the task before me was to find a qualified person to fill his shoes.Luckily enough three of my friends recommended Dr. Du..Founder and Principle of Sudbury Dental Smile Center of Sudbury.I couldn't believe the quality of care I received on my first visit! The staff is warm,friendly,

professional and extremely knowledgeable.The cleanliness of the clinic is impressive with its state of art dental equipment.Each of the examination rooms are equipped surround sound and flat screen tv so you can enjoy your choice music or just watch the news.Dr. Du is truly a talented,bright, seasoned professional which gives her clients a level of comfort that they can rely on.Her work is impeccable she's nothing less than a perfectionist.As a Sudbury resident for 40 years, we as a community should consider ourselves fortunate to have such a fine group of professionals in our town.

Everyone was so welcoming and accommodating. Kerry was very patient and allowed me to try on so many types of frames, but she was just enjoyable to be around and made me feel like I was shopping with a friend and not a doctor's office. The rest of the staff were very attentive and knowledgeable as well. Dr. Tomasino was wonderful and thorough. I felt like she took her time with my exam and her recommendations were intentional and helpful. Very happy with my experience!
