Meet Our Dentists
Dr. Sarah Park
Dr. Sarah Park is thrilled to call Massachusetts home and to provide compassionate care to children at Rock Street Pediatric Dentistry & Orthodontics! Dr. Park completed her Bachelor of Science in Biochemistry from Stony Brook University in 2006. She then attended Columbia University College of Dental Medicine and earned her degree of Doctor of Dental Surgery. Dr. Park has an extensive training background from Brooklyn, New York and Vancouver, Canada, in level one trauma emergencies, indigent care, and outreach experience treating people who are deprived of access to dental care in homeless shelters and community clinics.
Dr. Park was practicing as a general dentist in New York restoring smiles. Knowing the challenges a general practitioner faces with a reluctant patient has made her conscientious in the care of our youngest patients, so they can later seek care without hesitation. She has served as a chief resident while completing her specialized training in Pediatric Dentistry in Boston University to treat the most vulnerable and impressionable children and special health care needs with tenderness and patience.
She currently lives in Dartmouth. In her free time, Dr. Park enjoys hiking, biking, and spending time with her family and her kitties (Boo and Bella) and dog (Molly).
