Dr. Nicole Cornish


Dr. Cornish is originally from Martins Ferry, OH (a small town on the border of Ohio). I obtained a Bachelor in Psychology from Duquesne University and went on to the University of Pittsburgh to earn my Doctor of Dental Medicine and Specialty in Orthodontics. My husband, David, and I have 5 crazy kids with 12 years between the youngest and the oldest!

I chose to work with Bridge City Braces…

I had worked the majority of my 14-year career in corporate dentistry and was looking to change from that practice model. When I met the Martins and learned about their family-centered philosophy of dentistry, I couldn’t have been more excited to join the group!

What do I love about being an orthodontist…

Everything! Changing a person’s smile can truly change their lives (mine included). I love seeing the confidence that comes when the smile on the outside matches the beauty already there on the inside. And I love when someone tells me that their experience made them want to be an orthodontist.

What I love about working at Bridge City Braces…

Everything! The team that I work with at Bridge City Braces is like my second family. I have known many of the girls for years. They are always there to support me, lift me up when I’m down, make me smile, and always make me excited to come to work each day.
