I am a new patient at Dr. Dans and I must say I had a wonderful experience. His hygienist, Lizzi, is extremely thorough and makes you feel comfortable throughout the entire visit; not to mention the most gentle cleaning I ever had. Dr. Dan is very knowledgable and diagnosed problems that I was never aware of such as clenching my teeth! He was very informative. Him and his hygienist together are a great team, the best in New York by far.
