Gregg L. Kassan, D.D.S., P.C
If you are looking for a dentist that knows his stuff, Dr. Kassan is the one. He is thorough and fully explains what needs care and what needs to be done. He took pictures of two teeth of mine that needed crowns, and explained in detail why from the pictures. The dental hygienists are also top notch.

Kassan and his staff are great and give excellent service! With current condtions, I felt very safe going in because they are always very clean and I knew they would take the extra steps needed. At the family and cosmetic dental practice of Gregg L. Kassan, DDS, Dr. Kassan and his team know the importance of a healthy smile.

Ms. Bethany, the dental hygienist, provide excellent service. She was empathetic, had a gentle bedside manner, and would often let me know what she was about to do before she did it. Dr. Kassan followed up in an efficient and pleasant manner. No complaints!

Dr. Kassan and his team are professional yet relaxed. Both Dr. Kassan and Bethany told me exactly what they were doing while they were doing it and are thorough and kind. My husband and mother also go to Dr. Kassan and will continue to as long as we live in the Montclair/Woodbridge area!

Appreciated being acknowledged by name when I entered the facility. During the treatment I was made very comfortable and thank you Dr. Kassan and staff, as a Native Black person with the craziness going on with racial inequalities I felt welcomed. So appreciated the warm blanket, again as much as people despise the dentist, thank you, you guys are awesome!!!
