Belmont, MA Dentist

Dr. John Diune

Specialist in Pediatric Dentistry and Endodontics

Dr. John Diune was born in Taiwan and grew up in the Boston area when his family immigrated to America. With roots in Lexington, MA, he is thrilled to be practicing in this area. 

He is uniquely dual specialized as a Pediatric Dentist and Endodontist (Root Canal Specialist). He earned a BS in biomedical engineering from the Johns Hopkins University and a Doctor of Dental Surgery (D.D.S.) Degree in 2003 from the Columbia University School of Dental and Oral Surgery. After Dental school, Dr. Diune completed a General Practice Residency in Hospital Dentistry at the University of Michigan. Being intrigued by instrumentation and engineering, Dr. Diune returned to Columbia University where he completed his Endodontics specialty training in 2006.

Early in his career, Dr. Diune provided endodontic care to both adults and children and was the recipient of many Top Dentist awards yearly. During this time working with children alongside their parents, he saw an essential need for experienced specialists who understood the complexities of a child’s present and future oral and emotional health when faced with challenges such as root canal issues and potential loss of teeth. This need inspired Dr. Diune to return to training and completed a Pediatric Dentistry residency in 2017 from NYU Langone Medicine at St. Joseph Health Center in Providence, RI. 

Dr. Diune is a member of the American Dental Association, the American Academy of Pediatric Dentistry, the American Association of Endodontists, and the Massachusetts Dental Society.

Dr. Diune loves spending time with his wife Dr. Denise Chow and their two children, Sophie and Jacob. In his free time, he coaches girls and boys lacrosse, enjoys fishing, and raising their chickens.

Dr. Denise Chow

Specialist in Orthodontics

Raised in Lexington, MA and southern NH, Dr. Denise Chow is dedicated to serving the community she loves.  During her undergraduate years at Boston College, she studied biochemistry and studio art, and realized dentistry could combine both her passions beautifully.  She went on to complete her dental training at Columbia University, receiving her degree in 2004.  In dental school, she met her husband Dr. John Diune, and is very thankful she can share her career and life with him.  

She went on to specialize in Orthodontics because she loves the great reward that orthodontic treatment can provide for an individual.  In 2007, she completed her Orthodontics specialty degree at New York University.  While at NYU, she treated patients of all ages in the heart of Manhattan with Invisalign, self-ligating brackets and lingual orthodontics.  She loves that each patient has an individual orthodontic journey, and she is passionate about guiding each one to the same outcome- the best smile!  A smile makes each person unique, and Dr. Chow is honored to help each individual shine their smile.

Her favorite month of the year is February, which is National Children’s Dental Health Month.  She uses this opportunity to visit local preschools and elementary schools to share the importance of keeping our teeth healthy.  She is an active member of American Dental Association, American Association of Orthodontics, Massachusetts Dental Society and Give Kids A Smile.  Outside the office, she enjoys running, photography, cooking & baking, spending time with family and friends, and growing in her faith.
