Mark Bornfeld DDS...


...has lived most of his life in Brooklyn since moving there in 1958. He has attended P.S. 213 and J.H.S. 166 in East New York, and is a 1969 graduate of Brooklyn Technical High School. Mark earned his Bachelor of Science degree in 1973 from Brooklyn College, and his Doctor of Dental Surgery degree in 1976 from the New York University College of Dentistry, at which time he was inducted into the Omega Kappa Upsilon Dental Honor Society. He received his postdoctoral training at the Peninsula Hospital Center in Far Rockaway, NY, and with his twin brother Steven has maintained a private dental practice in Brooklyn since 1977. He is a clinical instructor at the NYU College of Dentistry, editor at the Queens County Academy of General Dentistry, as well as dental consultant at AllExperts.com. He lives in Mill Basin with his wife, Maria.

Steven Bornfeld DDS...

...has been a lifelong partner in Mark's peregrinations. Likewise a longtime resident of Brooklyn since 1958, he has followed an identical course of education, save for a one-year separation from his brother in fourth grade due to the misguided belief that twins should each find his own identity. He also attended P.S. 213 and J.H.S. 166 in East New York, and is a 1969 graduate of Brooklyn Technical High School. Steven earned his Bachelor of Science degree in 1973 from Brooklyn College, and his Doctor of Dental Surgery degree in 1976 from the New York University College of Dentistry, at which time he was inducted into the Omega Kappa Upsilon Dental Honor Society. He received his postdoctoral training at the Catholic Medical Center of Brooklyn and Queens, and has partnered with Mark in their dental practice since 1977. Steven lives in Windsor Terrace with his wife Marie and daughter Lauren.
