Dr. Matt


Dr. Matt Mannella is a board eligible pediatric dentist who grew up right down the road from Pediatric Dental Associates of Randolph. After spending so much time in the office shadowing his parents, Dr. Mannella and Dr. Arnold, Dr. Matt decided to become a pediatric dentist himself! He received his DMD from Rutgers School of Dental Medicine in 2019 and pursued his pediatric certificate at Children’s Hospital of Pittsburgh, where he received extensive training in dental traumatology, special needs care and advanced behavior management techniques. He is so excited to be a part of the Pediatric Dental Associates family and to serve a community he has known for his whole life!

When not making smiles happen, Dr. Matt likes to stay active! He is currently training for his first marathon, plays lots of golf, and in the wintertime, teaches snowboarding to children of all ages. Dr. Matt is also a bass player and loves to jam with friends to all types of music. Dr. Matt looks forward to meeting you at your next visit!

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.
