I wasn't planning to write this review, but someone from this office called me yet again to…read moreschedule a cleaning appointment. First and foremost, during my last visit, two roaches crawled out when an assistant moved my chart. This is a medical office, and there should not be bugs anywhere near patient records or treatment areas. In my experience, the entire office appeared very dirty. The floors looked as though they had not been swept in months, the carpet was stained, several counters and machines were covered in dust, and the office smelled like mold and dirty carpet. The main dentist regularly ran one to two hours behind schedule. Dr.Glasser introduced himself as a professor, but I could not verify his claimed affiliation with Columbia. I checked the hospital's website and called directly, but no one I spoke with had heard of him. During my last procedure, dr.Glasser answered his phone twice while wearing the same gloves he had put on to treat me. He then attempted to continue working without changing them. Even more concerning, he tried to begin treating my daughter without putting on gloves after he had been in another treatment room. He also walked in carrying a coffee mug and took sips during my procedure. He tried to convince me that I needed a root canal and crown on a tooth that, according to another evaluation, did not even have a cavity. Dr.Renee, who is his daughter, frequently interrupted his work to ask him to check what she was doing. He had to stop my treatment several times to assist her, which was frustrating and made me uncomfortable. The way he spoke to her--and to other staff members--also seemed disrespectful. The tension throughout the office was noticeable. Staff members were often on their phones or appeared to avoid him, and I saw different assistants during nearly every visit. I will never return to this office or bring my children there again. If you choose to visit, I strongly recommend looking carefully at the condition of the office and deciding whether you feel comfortable with its cleanliness and infection-control practices.

I've been a patient of Dr. Glasser for a few years now, and he is truly a master of his trade. He…read moredoes it all -- general dentistry, cosmetic work, gum surgery -- and he does it exceptionally well. I've had a lot of work done, and I've never felt any pain during any of my visits. Dr. Glasser genuinely cares about his patients. He always explains your options clearly and walks you through the process so you know exactly what to expect. The office is spotless and equipped with state‑of‑the‑art technology. The staff is wonderful too. His wife, and his daughter, Dr. Renee (also a dentist in the practice), are incredibly kind, and the hygienists are fantastic. You truly can't go wrong choosing this practice if you're looking for a great dentist. Thank you, Dr. Glasser, for everything -- you're the best!

If someone wood ask me to describe Dr. Ayoub in 3 words they would be Amazing, honest,…read moreperfectionist. My family & I have been coming to him for many years. Only dentist my boys, as myself, feel comfortable with. Honestly. I was there for a procedure last week (one of many) & thought tooth couldn't be saved, however he saved it!! :):) His office called the next day to see how I was doing & went in that following day as check up. This is just one of many visits I've experience with this dental office. When you find a dentist that you & your family are comfortable with (which is hard to find) its a very good feeling. With my experiences with Dr Ayoub I highly recommend!! & give 5 stars. If anyone has any questions on particular procedures, if I had them I will be happy to share.

My husband, my 2 boys and I have been seeing Dr. Ayoub since 2012...and I was referred to him by my…read moremother when I moved to Long Island from California and she, at the time, had been his patient for over 13 yrs! Needless to say he's our family dentist and more...! I say more only because he provides more then your average dental care. He has always been thorough with his treatment plans, he takes the time to discuss and understand your personal situation and most importantly he always considers your budget and gives you options. His new facility is absolutely state of the art to say the least..you never need to leave to go to any other place to get tested or X-rays. His staff is competent to handle everything in-house. I got my veneers last year and I couldn't be happier! I have had extensive work done on my teeth including root canals, on lays, fillings, etc. and I'm going in next week for my implants knowing everything will work out fine. My boys love seeing him, they used to be deathly afraid of seeing a dentist and now all I mention is Dr. Ayoub and they're in the car, ready to go! If I could give him more then 5 stars I would!!!

I have been seeing this dentist Dr. Boris Yusupov for a year. Initially he was good to deal with…read more On my second visit I needed a root canal. He did half the job and charged me $250.00 although I had Insurance. (The fee was never discussed before the procedure.) I paid the amount and delayed seeing him till yesterday. I called his office on Tuesday, the 29th for an emergency visit and was granted an appointment at 12N. (July 30,2025) I reached there around 11:30 as I was parking my car I received a call from the receptionist informing me that my appointment had to be rescheduled because they have "equipment problems". I said I am already at the door and all I needed was for him to look at my tooth (10 seconds) to see if I am infected. I was in pain. She agreed and I walked in. There was one patient waiting, she was taken in, and as I am sitting there, two more patients walked in. One after the other they were taken in. The "equipment trouble" was a big lie. I sat there for two hours and finally walked out and called the receptionist and told her how I felt about the situation. She apologised to me. If the Dr. did not want to see me due to any reason, all he had to inform me was he was busy. I went there with an appointment. I always felt that he was very unprofessional and rude and no manners. He is an immigrant like I am. I do not know what I did to him to hate me. He is hungry for MONEY. If you notice, majority of the positive reviewers are all females. Sorry, I could not give a negative star( -*) I will never ever set foot in his office. Please stay away from this guy.
