I've been seeing Dr. Gainor for over a decade. His professionalism, knowledge, and unwavering quality in his craftmanship are the reasons there is no other dentist I'd want to be working with.

My experience with Dr. Gainor and his team for all my dental work (for many years) has always been excellent. I highly recommend him if you have a dental issue.

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.
