“A great smile is a facelift in everyone’s price range.”

David A. Zadik DDS

Dr. David Zadik’s commitment to continuous education and professional excellence began many years ago. After earning his undergraduate degree in his hometown from the University of Toledo in Ohio, he went on to complete his dental graduate work at the University of Detroit Mercy in Michigan, followed by residency programs at both Detroit Mercy and Mt. Sinai hospitals. He then added to his expertise by engaging in rigorous advanced training in the field of restorative cosmetic dentistry. In the years since, he has continued to seek out educational opportunities in new technologies that are transforming dental care and cosmetic options for today’s patients.

After establishing his practice in New York City in 1990, Dr. Zadik quickly gained a reputation for superior restorative and cosmetic dental care. As his Manhattan practice grew, he built an additional practice in Greenwich, Connecticut, which has allowed him more ready access to both his family and patients in that community.

Dr. Zadik has served on the teaching faculty of New York University Dental School and Bellevue Hospital in New York City. He belongs to the American Academy of Cosmetic Dentistry and the American Academy of Laser Dentists. He is also a member of the American Dental Association, Academy of General Dentistry and Connecticut State Dental Societies.

Dr. Zadik enriches his own life by contributing his professional skills to those less fortunate. He has joined teams of physicians and dental professionals as part of “Doctors without Borders,” “World Challenge” and “Partners in Health.” These efforts support and provide medical and dental care in disadvantaged areas around the world, including Haiti, Mexico, Guatemala, Belize, Honduras and Costa Rica.

Because Dr. Zadik believes that goodwill and compassion should begin in one’s backyard, his dental team also provides children with complete dental care through the “Kids-In-Crisis” Organization in Greenwich, Connecticut. These services are free of charge to the disadvantaged children in surrounding areas.
