Nicholas Pappas is originally from Long Island, New York. He attended Pennsylvania State University for his undergraduate degree, followed by SUNY at Buffalo School of Dental Medicine for his DDS (Doctor of Dental Surgery), where he graduated magna cum laude. He then went on to complete a hospital-based General Practice Residency at Stony Brook University Hospital where he gained valuable experience treating patients with dental trauma and infection.

He is currently board eligible.
