I've had a really frustrating and honestly disheartening experience with Great Expressions Dental Islandia. I originally went in for a routine cleaning that my insurance covered, but I was told they wouldn't do the cleaning unless I agreed to an out-of-pocket "deep cleaning" that I've also been told by their hygienist that I don't actually need. I was told to wait six months and then they would do the routine cleaning without requiring the deep cleaning, so I did exactly that. I came back for my appointment yesterday, and once again, they refused to do the cleaning. That already left me feeling really uncomfortable and pressured. On top of that, this has become a pattern. About six months ago at my last appointment, I was told they couldn't do my cleaning because the hygienist had left early. The next time, I was told she was "too busy" to fit me in, even though I had scheduled the appointment months in advance. Every time I go, there always seems to be a different reason why the cleaning can't actually happen. Yesterday, I showed up and was again told the hygienist had left early. I don't understand how this keeps happening when patients are already scheduled. Then I was told to come back today specifically for the cleaning. I made the appointment, and I was already on my way there when I received a call shortly before my scheduled time saying they would not do the cleaning unless I agreed to the same "deep cleaning." This is something my insurance does not cover because it is not deemed necessary, and I've been told by the hygienist herself that I don't need it, it was just recommended. I've also had appointments where I've waited a long time past my scheduled time, only to be told last minute that things were changing again. It honestly feels really upsetting and frustrating to be on my way in after rearranging my day, only to be turned away once again for the same reason. I always try to be understanding, but at this point it feels like my time and care aren't being respected or prioritized, and that's been really disappointing. Just sharing this in case it helps someone else advocate for themselves or think twice before booking with Great Expressions Dental.

We lived in Queens but we would make the one hour trip to Long Island for our dental visits. Impractical, but worth it. LOCATION- Building is right by the highway; parking is plentiful; and during long waits, one can go shopping in nearby commercial areas. Lots of places to eat, too, in case your appointment falls around lunchtime. OFFICE ATMOSPHERE- The dental office isn't too fancy nor intimidating. It's just a neat, normal-looking office. The waiting room has a t.v. and an aquarium with live fish resembling characters from Disney's Finding Nemo. It's also clean and quiet. STAFF- We had a pleasant experience with the staff who worked on us. They were always friendly to us and made small, meaningful talks. And, during our weekly visits, we had to bring our daughter, who was only a year old at that time. Never did we feel any bad vibes about bringing our child to our appointments. In fact, some of the staff would play with our daughter when they weren't too busy. Also, the hygienists are quite good in what they do. I appreciated them more since the hygienist in our new town, I think, has heavy hands. DENTIST- We are glad to have come across Dr. Calvet. She is very motherly but professional. I think she has the knack of making her patients feel comfortable with her so that they can trust her. After all, dental visits are very, very intimate. She explains what she is doing or what she plans to do. My husband has very bad dental hygiene but she doesn't scold or embarrass him for that. We stopped going to her office when we moved Upstate but we have to say, she did a good job with our teeth. Our new dentist was amazed when he saw the work on our teeth. He had only compliments for them.

"Meh. I've experienced better" is exactly right…read more The women at the front desk were very nice and helpful. This review is solely on the actual appointment I had and the experience. To cut a long story short (I like to say that, but that never actually happens) I was going to a GREAT dentist, but switched over because they didn't accept my new insurance. Googled a few places and came across this one, I didn't really do much research, it was one of the first options that popped up. Day of my appointment, I thought I was coming in for a cleaning, well - turns out it was just x-rays. Okay, cool. I sat in the chair, dentist comes, says hello and does the x-rays. I ask him a few questions and he's mumbling. I couldn't hear him, and he repeated what he said, but again - so low and mumbled. He kept saying "they'll tell you at the front desk" and that was it, walked out. I don't know about you, but I like my dentist to be friendly, tell me whats going on in my mouth, what I need, etc. Nope - he cut it real short. Barely said 5 words to me. The front desk tried to squeeze me in, but they're so booked - i was looking at a month out just for a cleaning! I then decided to check yelp reviews, and a family member laughed when I told them I came here, they said "didn't you check the reviews? I hope you're just passing by it & not getting any work done" Lucky for me, my old, favorite dentist - now takes my insurance. So I switched back over!

My family and I have been patients with Dr Jay for over 15 yrs, when he was in the Coram office but since moving to this location in Central Islip the professionalism regarding the receptionist has tumbled for the worst. I had received approval for work to be done so when, I received notification from my insurance company that it was approved,I called and spoke to the receptionist who said the person who was familiar with my chart wasn't in the office.
