I am not one to write negative reviews however, I feel the need to with The Smilist Dental…read more It's a shame after over 20 years of visiting the same dental practice, I've decided to leave with my family. Since The Smilist took over Dr. Silon's private practice, service continued to decline, particularly the front desk staff and billing. We often experienced inaccuracies with billing and then, good luck with contacting the billing office, the phone number printed on the billing statements is non-operational and desk staff were often rude and annoyed when questioned about discrepancies. In addition, managers frequently change; dentists come and go; rules of the corporation often change too. I reached out to corporate multiple times requesting to speak with upper management, both telephonically and electronically, and still to date, over a month later, no response! After being advised by the call center that I will be contacted by the Regional Manager, Ashley Adornetto within 24 hours, I'm still waiting since my calls on April 6th, 10th and 23rd. I haven't received an email reply either! It's unprofessional and disgraceful that a corporation with so many offices operates in this manner. Not to mention, the unprofessionalism of Judy and Joanna from the RVC office passing comments to their manager Maria about "needing drinks" after she had a lengthy conversation with me, over billing on April 7th, when they thought that she hung up the phone. If you wonder why we stayed as long as we did, it was due to a few of the staff that I will name who were fantastic, Dr. Funk (retiring this month) and two hygienists who we loved, Lelia and Roberta. We will miss them but that's it!

I have waited well over a year to put to words my experience with Dr. Hasday…read more I went to him to have an implant done. The experience went smoothly until a couple of days later when my face started to swell. I went back to Dr. Hasday's office and was given a stronger antibiotic to combat the infection that was beginning. Another couple of days and the swelling didn't go down, in fact, the swelling began to spread. Went back to Dr. Hasday, his exact words were that he "was not worried at all" and to wait for the antibiotics to take affect. Two more days later, I went back to his office for the third time. I was told to go to the hospital immediately as it seemed that the infection was spreading down my neck and up my face. I ended up spending FIVE DAYS in the hospital. And that's not even the worst part of the story! Dr. Hasday, while attentive when the implant failed and while I was in the hospital, soon began to ask for payment! Payment for a failed implant that left his patient in the hospital for FIVE DAYS! I thought that there must be a mistake and he assured me that he had to seek payment from me because it could show fault on his part if he didn't! Ultimately, he did return some of the money that I had already paid. Then it was time to re-attempt the implant. The negotiations were on again! I stupidly paid, again, to have the implant done with his office. SECOND IMPLANT ALSO FAILED! So, thousands of dollars spent, 5 days in the hospital, one terrifying infection, one infection/implant removal surgery and still no implant. I recognize that some of what happened was out of Dr. Hasday's hands. However, how he comported himself during one of the worst times of my life, is all him. This is a doctor that does not care about you. Trust me. By the way, I am still receiving calls from his office for payment.

This current office, as was the last one, is always immaculate. It feels good to walk into a clean and tidy business. With the pandemic looming, he has taken even more stringent measures.

Untrustworthy and deceitful. Those are two words that describe Grosser…read more Going to Grosser is one of the worst possible decisions you can make if you care about your teeth. My records were sold to Grosser when my previous dentist retired. I should never have come to him. I had a cracked wisdom tooth and went to Grosser. He told me that the tooth was fine, even though I could clearly see the crack in the mirror. I ended up going to another dentist after a piece broke off, who then directed me to have an oral surgeon extract it. Grosser also performed a root canal and crown on me. The process of getting the crown was drawn out to nearly 3 months. When I was feeling pain on that side of my mouth the weeks after, I went to a different dentist to have it evaluated and see if a filling near the crown was loose, as that is what Grosser had told me, and inquire if that was the true source of the pain I was feeling. The dentist examined me and told me that there was no loose filling, and showed me an x-ray of the crown, showing that the remaining tooth had been fractured and crown post dislodged, all in the course of a month after receiving it. Now I am in the process of getting a dental implant due to his botched work, but at least I know to never visit Grosser again and let a different dentist handle it. Fillings from Grosser were difficult to floss. Even the best floss would be torn apart trying to pop it out of the space around the source of the filling. This same situation not just to me, but other family members. Different dentists that we have visited after have all been surprised by things such as 1) oversized fillings at risk of breaking, and 2) his over-enthusiasm for crowns and shaving off way too much tooth. Grosser is clearly not implementing the best practices under best practices. When a family member asked him about the difficult flossing, Grosser straight up lied and said there was no issue, even though he himself could not even get the floss out of the gap. I'm sad that I have Grosser so many chances. I should have just trusted my gut and went elsewhere after the misjudged broken wisdom tooth (the crown was unfortunately done beforehand). After my misadventures here, it is clear that he does not put his patient's best interests first, and his shoddy practices cause more problems than they solve. There are much better dentists on Long Island and in the RVC area that you can go to who actually care about their patients and have up-to-date equipment and techniques. Grosser honestly deserves to lose his license to operate. Do yourself a favor and go elsewhere before you get hurt.

My son had an impacted molar that needed to be removed. Dr. Richard Mirra did the procedure and my son is fine. However, when we made the appointment we told them that he didn't want general anesthesia. But when my son arrived he was told the doctor cannot do the procedure unless he has general anesthesia so he signed for it. A couple of years ago he had an impacted molar removed at a different place and did not have to do general anesthesia. Long story short, the insurance company denied the claim. They will not pay if it's not more than one extraction. I called the office and they said they will resubmit the claim with additional information. It was rejected again. So I called my insurance to find out what additional information was submitted and why wasn't it paid? They said the office submitted a letter indicating that the reason they had to do general anesthesia was because my son suffers from anxiety and phobia from a previous trauma. This was a lie and a false claim. When I called the office I spoke to the office manager, her name is Christine. I wanted her to explain why they submitted this false narrative? If the doctor felt he needed to go under, why not just explain why? I could not believe how nasty this woman was! She was not just rude, she was condescending and told me it was common practice to send these letters. She thought she was doing me a favor. It was clear that they just wanted to charge extra for the anesthesia and I didn't feel I should have to pay almost $500 for something that was not medically necessary. So I figured since my son signed for it, we should at the very least split the cost, reduce my bill. This woman berated me on the phone and eventually hung up on me. I decided to drive to the office, but by the time I got there the office was closed. On the way to the office another woman calls me and tells me if I pay the bill now she will reduce the bill by 50%. This is what I asked for to begin with! CHRISTINE expected me to just pay the money. I did not have a good night. I couldn't stop thinking about how condescending CHRISTINE was. After all I am a customer. Isn't that the reason you're in business. Is this how you treat all of your customers. I decided to go in person to speak to the doctor. It's his private practice and he should be aware of how his patients are treated. Well NOPE! He not only didn't come out to speak with me but they called the police on me! I spoke to the cops and it was all fine. I am pretty sure that I am not the only patient CHRISTINE treated that way. I wanted her to know that this is not ok! She should be working in a back room with zero interactions with customers! Disgusting Customer Service!! Shame on these doctors who continue to employ people like this!
