Dr. Farajian


Dr. Sara Farajian is a board eligible pediatric dentist. She completed her dental education and training locally, receiving her DDS from New York University College of Dentistry, as well as performing her General Practice Residency at Hackensack University Medical Center and her pediatric dental residency at Montefiore Medical Center.

Dr. Sara’s dedication to providing exceptional care for her patients comes naturally to this mom of three young daughters. When she is not creating smiles in the office, Dr. Sara makes smiles at home with her girls baking her family’s favorite chocolate and cinnamon apple cakes. She can also be found exploring local parks with her family and friends, and when she can steal some time to herself, Dr. Sara retreats to her hobby of oil painting.
