ALL ABOUT THE MONEY! My son appeared for his appointment with Dr. Zatcoff. The office manager, Stephanie, told him that they did not accept his new insurance. He agreed to leave without service. To his dismay, Stephanie told him that if he left, he would have to pay $75 for a "NO SHOW" fee or $155 for treatment. It became an embarrassing situation as other patients were in the reception area. This is quite UNPROFESSIONAL, UNETHICAL and COERCION since my son agreed to leave without treatment when she said they did not accept his new insurance. We left several messages for Dr. Zatcoff and he has not returned any; quite unprofessional. We have been patients there for numerous years but, this incident will end our professional relationship with Dr. Zatcoff. I must state that we have no issues with Dr. Zatcoff but, will not tolerate this unprofessional, humiliating and embarrassing situation that our son had to endure. The office should have checked to ensure that they accept insurance from patients prior to the visit instead of expecting patients to pay a "NO SHOW" fee if the patient arrives and they do not accept the insurance - please explain when does the negligence of the staff becomes the responsibility of the patient. Please remember, without patients this office cannot survive therefore, professional ethics and empathy for all must be established and re-enforced. This submission is by the mother, Karen, who is still awaiting a call from Dr. Zatcoff; unacceptable behavior exhibited by Stephanie to my son and me when we spoke.

The Staff was courteous from the moment I made my phone call to schedule my consultation. The office staff was great! Including the ladies in the front and my ex-ray tech, Dr. seid, explained the steps needed to be done and given his advise I can tell that he really cares about the well-being of the patients. In all I had a great experience. I finally found a dental Office I feel confortable with and I can recommend to my friends and family.

The best dental care I have ever experienced, some years ago I had my cap done by my former dentist and it took them 3 months from start to finished, even the temp cap kept falling off. Yet it took beautiful smile 2 weeks for recap, even the temp feels and look real. The staff was great. Very welcoming and friendly. The dentist was very nice and informative, and if you're afraid of needle trust me. This dentist is so smooth you won't feel a thing. Best Ever !

The services that I received at beautiful smiles of Long Island was excellent. Dr Seid and his staff were professional and sensitively oriented to meet their Client's needs. They listened and were opened to discuss my concerns. I am very pleased with my oral results and would highly recommend them to others. I'm enjoying my beautiful new smile. "Ready for my closeup".

I found Dr. Seid through my insurance company and I'm so glad I did! He is a caring, professional and outstanding dentist. He took the time out to explain all treatments on the first visit and all visits have been very stress free! The office staff is also super friendly. Highly recommend!

Had to wait a long time for the doctor. I went in for cleaning but the doctor started talking about doing other procedure to my teeth and those service will be pay out of my pocket. I said I will let you know because need time to think about it but he continue to insist that I make another appointment for those out of pocket procedure . He didn't clean my teeth and said you done for today. He charged my insurance company for cleaning which he did not do.

I've been coming here for almost half a year now and can't stress enough how much the staff makes you feel like family. I have been struggling with GERD for a year now which has completley destroyed my teeth. Dr. Seid and the incredible team at this dentist office have been working on my teeth and doing as much as they can to help me and my situation. I've never seen a staff so dedicated to a patient and their health as much as this one! They are truly spectacular and they've literally saved my life.

I have been a patient at Beautiful Smiles for five years. This is really a wonderful dental office. Once I check in at the front desk I don't have to wait too long to be seen to. Dr. Seid is a great dentist. He has done a couple of procedures for me and I always come away very satisfied with the work he has done. Emma, my dental hygienist did an amazing job checking and cleaning my teeth. She was so gentle and thorough with cleaning my teeth. I am so glad that I finally have a great dental office to always go to for any dental concerns. The receptionists are also very kind and helpful.. I also wanted to mention that the facility is very clean. I am very happy to be a patient here.

It's been a year and a half since I went to the dentist due to COVID. My last dentist dropped my insurance and I was looking for a local dentist then Covid hits. I found another dentist who found a lot of work that I needed to get done over 7k to be exact. I was a bit skeptical about it and went to Dr. Gabrielle for a second opinion. It turns out I needed only some work done and the rest was made up. He was kind, spent time with me going over what was fake and spoke about why I needed the actual work. He was patient and was able to do my tooth extraction and implant in his office. Im so glad I found him as a trusting and caring dentist. I truly believe he wants what right for the patient and will do the very best work possible to achieve it. Thanks Dr. Gabrielli
