Dr. Sara

Board Certified Pediatric Dentist

Dr. Sarunphorn Rasamimari “Dr. Sara” grew up in Bangkok, Thailand where her passion for pediatric dentistry started with her own childhood dentist. Inspired by seeing how fun and compassionate she was, Dr. Sara knew that this was her calling. Dr. Sara wants to ensure that all of her kids will grow up to love the dentist as much as she does by making sure that each appointment is not only educational for the parents and patients, but also very enjoyable while providing the best of care. Her goal through education is to teach lifelong habits that her patients will be able to take forward into adulthood.

Her passion in prevention and minimally invasive dentistry was recognized when she was published in the prestigious Journal of American Dental Association on the use of Silver Diamine Fluoride.
