Merrimack River Dentistry - Dentist, Hygienist, and Staff


All our staff members are highly trained with many years of professional experience and dedicated to provide the best possible dental service.

Merrimack River Dentistry Staff
Merrimack River Dentistry started in 2014 with Dr. Yoon purchasing the practice that has been in place for many years. Since then, we have been steadily making our office more modern, more friendly, and more convenient while keeping our dental care at the highest level. We utilize state-of-the-art dental equipment such as latest Dexis digital X-ray and Cavitron ultrasonic scaler.

We work together to make your visit enjoyable and efficient. We continue to improve our skills by attending Continuing Education classes and Yankee Dental Congress. Excellent dental care is our highest priority. Once you visit us once, we are sure that you will stay with us for all your dental care.

Dr. Yoon graduated from Vanderbilt University in Nashville, TN and earned her Doctor of Dental Medicine degree from Boston University Goldman School of Dental Medicine.
