Justin Kotliar, M.D.

Justin is a lifelong North Carolinian (there’s no barbecue like Carolina BBQ). He grew up in Chapel Hill, attended Duke University for undergrad and East Carolina University for medical school, and only left the state in 2018 when he moved to Manhattan for his residency at NYU Langone. He is so glad that he did! To Justin, every day feels like a new adventure and he falls a little more in love with the city at each turn. He currently lives in Midtown with his wife and their very opinionated rescue cat Nox. They love exploring the city and especially love trying new restaurants.
