About Atlas Pediatric Dental Care in San Tan Valley, Arizona

Matthew C. Herring, D.M.D.

Pediatric Dentist


Dr. Matt loves his home state of Arizona and is excited to be in the San Tan Valley. One of his favorite things about being a pediatric dentist is interacting with his patients. He is committed to helping them achieve their best oral health in a fun, relaxing environment, which typically includes singing, laughing, and fun scrub tops.

After receiving his undergraduate degree at Brigham Young University—Idaho, Dr. Matt attended the University of Nevada Las Vegas School of Dental Medicine for his doctoral degree. He also completed his two-year postdoctoral residency in pediatric dentistry at the same school. Dr. Matt is a Diplomate of the American Board of Pediatric Dentistry (ABPD), meaning he is a Board Certified Pediatric Dentist. 
He is also a member of the American Academy of Pediatric Dentists (AAPD), the American Dental Association (ADA), the Arizona Dental Association (AzDA), the Central Arizona Dental Society (CADS) and the Arizona Academy of Pediatric Dentistry (AzAPD). He maintains his certification in both Basic Life Support (BLS) and Pediatric Advanced Life Support (PALS).
He has a conservative approach towards dentistry and prefers to retain as much of the original tooth structure as possible. His top priorities are keeping his patients safe, helping them to have a good experience and finding the best solutions for their dental needs.
He currently lives in Gilbert with his wife and their three children. In addition to spending time with his family, he enjoys biking, Legos, Star Wars, singing, and learning how to do new things. He speaks English and Japanese.
