He graduated from the University of Pennsylvania in 1991, with a major in Design of the Environment, and minors in Biology and Chemistry.

There, he did a one-year hospital-based residency treating medically compromised dental patients in one of the foremost transplant centers in the United States. Seattle is a great place to live, so Dr. Cooperman stayed there for over two years practicing general dentistry.

He returned to New York in 1998 to begin his specialty residency in orthodontics at New York University. He opened his practice in the Bronx in 2004, and has been working there ever since! Dr. Cooperman teaches at Jacobi Hospital in the Bronx, and is also on the faculty of the Albert Einstein College of Medicine.

He has been inducted into the Pierre Fauchard Academy, and the American College of Dentists. In 2017, Dr. Cooperman was honored to be elected President of the New York County Dental Society, one of the largest local dental components of the ADA with over 2000 member dentists.

In his free time Dr. Cooperman enjoys cooking, reading, running, traveling, and spending time with his family. He runs so much because he also really likes to eat.
