I have been seeing Dr. Gainor and his staff for many years. (15+)
They are all exceptionally friendly and caring. Dr. Gainor has a very hands on caring approach. The quality of care is beyond first rate. He is an artist.
As an example, I had a tooth that split to the root. He was honest and made clear that it was possible that the tooth might not be saved, but would do everything that he could. And he did. He WAS able to save the tooth. He made a crown that works perfectly. He saved the tooth. I know other doctors would not have tried.
Daniel D.
Totally professional expIain procedures and office is spotlessly clean. I have been a patient for many years. Dr Gainor is an excellent dentist as he anticipates problems etc. One of the best!
Alfred G. J.
He is the best dentist in NYC! Dr. Gainor is top-notch at what he does and is a true professional. Before I met Dr. Gainor, I was petrified of the dentist because of my prior dental experiences. Dr. Gainor and his staff are warm and compassionate and make you feel right at home. Dr. Gainor is extremely good at dentistry and a perfectionist at what he does. He truly does incredible dentistry and makes your teeth look their very best. His office is clean and neat. Their covid-19 protocol and protections are top notch and you will be in good hands in his office where safety comes first. I highly recommend Dr. Gainor to anyone looking for a highly skilled, thorough, honest and kind dentist.
