Dr. Hui (Julie) Yu D.M.D.

Dr. Hui (Julie) Yu D.M.D.


When Dr. Yu was young, she and her family moved from China to the United States in search of their next great adventure. For most of her early life, she grew up in Pittsburgh. She received a BS in Biology and a BA in Anthropology from the University of Pittsburgh. Despite her childhood fear of dentists, she furthered her education by becoming a doctor of dental medicine at Pitt followed by a year of additional training at St. Elizabeth Mercy Hospital, Youngstown, OH. It was her traumatizing experiences at the dentist that motivated her to want to change people's perceptions of their dreaded dental visits. Therefore, she is very understanding and empathetic towards patients with dental fear. Most importantly, Dr. Yu wants to maintain a relaxed atmosphere with her patients so that they feel at ease. She wishes to inspire trust and establish good rapport with her patients through her willingness to assist them to reach a better state of health. This is because she believes that a beautiful and functional smile is what makes the dentistry profession worth it. 

Outside of the clinic, Dr. Yu enjoys spending time with her friends and family, in particular food-related activities. She also likes to travel, bake and partake in experimental cooking, as well as cuddling her newly-adopted kitten.
