Dr. Altman is a terrific doctor, gentle, highly professional and careing. He is one of the best I have seen and I have really bad teeth - so this says a great deal about him. It’s fantastic that this practice, unlike many others come in on the weekends to care for their patients emergencies.

I went to Greenwich Dental Group, and had a cleaning by Brenda. She was careful, and compassionate, and I was thoroughly satisfied with the results. I have been a customer at GDG for over 20 years, and I completely trust the dentists there. Drs. Zadik, Altman, and Hotchkiss have always taken fantastic care of me. They receive my highest recommendation!

I practice what I believe are the 4 C’s in dentistry: Compassion, Courtesy, Competence & Cleanliness.

Steven Altman DMD,FAGD

Dr. Steven Altman received his doctorate of Dental Medicine degree from Temple University’s Kornberg School of Dentistry and completed his Advanced Education in General Dentistry residency program at Lutheran Medical Center in New York. He provides comprehensive dentistry services including cosmetic dentistry, implant dentistry, TMJ disorders, sleep apnea and restorative dentistry. Dr. Altman prides himself on utilizing state-of-the-art dental technology and research to provide the best care to his patients, meticulously detailing every procedure, whether it is a simple filling or a full mouth makeover. He is committed to listen carefully to his patients to understand their interests and concerns so that he can collaborate with them to achieve the best possible results dentistry has to offer.

My mission is to fulfill the needs of each patient that I meet in a personalized and comprehensive manner to restore confidence in their smile and life.

Marc J. Novak DMD, FAGD

Dr. Marc Novak was awarded his doctorate of dental medicine (DDM) from the University of Connecticut and completed advanced restorative and surgical training at the No. 1 hospital in the state of New Jersey, Morristown Medical Center. Dr. Novak believes in a conservatively proactive approach to dentistry with a level of personal attention to patients that has become central to the philosophy of Greenwich Dental Group. His comprehensive planning is carefully crafted to treat all levels of oral healthcare in order to provide you the care and commitment that you deserve.

Dr. Zadik

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

David A. Zadik D.D.S.

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.

Ultimately, the quality of my dentistry has to speak for itself, but it is also vitally important to me that my patients feel comfort and peace of mind with every visit.

Stephanie Hotchkiss D.D.S. Emeritus

Dr. Stephanie Hotchkiss is a graduate of the University of Maryland School of Dentistry and completed her residency at University Hospital in Baltimore. Prior to her joining Greenwich Dental Group, she served as director of the Department of Dentistry at Kernan Hospital in Baltimore and director of the Hospital Dentistry Clinic at Bexar County Hospital in San Antonio, Texas.
