Dr. David Liebes, D.D.S.


Dr. David Liebes is a 1988 graduate of New York University College of Dentistry. After a year of residency at the Veterans Administration Hospital in East Orange, NJ, he opened a private practice in midtown Manhattan and in 1996 opened an office in Livingston, NJ. He relocated to Hackettstown in 2005 and acquired his practice in Long Valley in 2015.

Dr. Liebes continues to take extensive continuing education courses to stay current with the most up-to-date dental procedures. He is part of a study club comprised of other general dentists and specialists that meet regularly to discuss a wide range of topics. Topics of discussion include presentations on special cases encountered within their own practices.

Dr. Liebes stays very busy outside of the office! He doesn’t mind enjoying an afternoon on the golf course, training for his next half marathon, or spending time with his wife and twin daughters.
