They really take the time to explain everything and make you feel comfortable. The staff is amazing. Thank you guys. read more

God awful. Two main issues: sexual harassment and overall negligence. I have made formal complaints to the NY Dept of Health, my health insurance and the Bayside offices. Overview: May 17, 2025, Dr Thomas repeatedly talked about women's breasts to me as he was cleaning my teeth. I am not a woman, regardless, that Dr Thomas who had never seen be before felt perfectly as ease talking and even singing about women's breast for over 20 mins leads me to believe there is widespread sexual harassment at this facility. And yes, it is sexual harassment even if you are not the object of sexual desire. I didn't ask for his comments. Dentistry has nothing to do with the female anatomy. Nov 21, 2025 (today) I saw Nikki. Her erratic behavior, negligence and constant distractions made me end the appointment shorty after it began. I first told her a sanitized overview of how inappropriate Dr Thomas was to which she immediately told me to "watch what I say". She made statements unrelated to the appointment like "I already had a meltdown over my phone today". I didn't know if this was a conversation opener, if she was on blue tooth, or just sharing thoughts. She also would break into song. She refused to acknowledge when she was being painful in cleaning. She threatened that if I didn't relax the instrument would be "dangerous" in my mouth like a "chainsaw". I'm 51. Going to the dentist isn't a new experience. These threats and dentists singing and talking about breasts are NOT common. When Nikki refused to acknowledge my audible discomfort, my hand signals and gestures, I ended the session. There is something deeply problematic about this location and staff. No one has followed up on my complaints about Dr Thomas. There seems to be a defensive wall to protect foul behavior. I know I am not an isolated case. Do not go here under any circumstances. read more

I transferred to this clinic because of insurance coverage when my Primary became out of network. BIG MISTAKE. My first day of evaluation went great with Dr. Gloria, but her prophylaxis lasted for just 10 minutes...This should have been a red flag. The nightmare was on my follow-up: 1. I came in on time for my appointment at 9 am (opening) and at this point there was only 1 person ahead of me. 2. 15 minutes later they called two patients , one that was ahead of me and another that came after. I figured that later individual might have same appointment time as I was. 3. But then, 30 mins later 2 more patients came and they were called before me, one without an appointment as I overheard it. So I got up and approached the front desk to ask what's goung on? they assured me Ill be called next. 4. 15-20 minutes later, they called another individual that came way after me. This is the line that definitely pissed mne off. Completely UNACCEPTABLE. The front desk who cant even speak straight English already collected my copay upon registration at 9 am. So, I asked for their manager to askfor explanation? Dumbfounded, She had no explanation to offer, and between her and reception and the aide - they didn't even know what my appointment was for? When clearly they called me to set this up. I was dumbfounded after that - so please beware, this clinic is very unprofessional, Thank God I got my copay back. But what prompted me to write this is their disorganization. Later that day I was called for an apology, unsincere, to which I informed them I AM NEVER GOING BACK. Fast forward today - They called me to ask me to set up a follow-up appointment and told them again I am not going back. Alas - I received 5 more calls for the same reason to set up an appointment. Dont want a clinic with SHORT TERM MEMORY LOSS to take care of me. Be very afraid. read more

don't go there! they don't care about your health. they will take your appointment just to start immediately and get the money from your insurance. I had an awful experience. very unprofessional team read more

My biggest complaint in the lack of customer service. I will not be coming back to this clinic. The first time I walked in, I was waiting at the front desk for 10 minutes and was not helped or directed where to go. Then, the receptionist came back and told me to sign in at the computer. I was so confused and had never experienced this operation of sign in. Keep in mind, I am 22 years old and tech savvy so you can imagine how an older patient may be confused as well. The first 2 appointments I had, I saw multiple patients express difficulty with something. Either scheduling, insurance, language, customer service. However, I wanted to give the benefit of the doubt because I hadn't received care from them and wanted to form my own opinion. I came in for a cleaning a month ago and then scheduled 2 appointments for fillings. The first apt was okay, but I showed up for the second apt the following week and was told I didn't have an apt today. The receptionist did not apologize, but she said she would see if the doctor could still treat me today. 20 minutes later I got up and told her I just wanted to reschedule a different day. The next apt she could get me is in another 45 days. read more

I had my first visit today. Everyone was so nice and Dr. Espinoza and her assistant took great care with X-rays, exam and cleaning, along with creating a dental hygiene plan for me. read more

I do not recommend Arista Dental . They have a lack of appointments system. They keep changing your schedule without your knowledge. If you do not back up yourself with a card from them in regard the date and time you are lost. The service with Dr Leeann was the worst experience that I have in my life. I went for a crown procedure and she did not make any effort to help to make the experience less painful. You treat me in a brutal way without no patient or concern for the way I feel in an open wound , not even provide anything for the pain prior the procedure. A Dr without heart. I can compare my procedure, because is not the first crown that I needed and the way she went with me was not wright. I will not sent any body to the kind of a dentist . Also Arista charge all your procedures, even when you did not even been finished the job. Some is wrong with that center . For me I will not give them not even 1 star . It is the worst that I have with a dentist in my life . read more

1st time here & I had an amazing experience. No complaints at all! I was seen less than 10min after my appointment time. Check in was easy. All of the staff were friendly. The dental assistant & dentist were friendly, knowledgeable & did great at their job! read more

- - - please take away the star! Since June'23 I have been waiting for the approval for a root canal and cap; the approval request was not submitted, then on November'23 I received a claim denial from my insurance; I contacted my insurance for more information. I mentioned to the insurance the work has not been done and that I needed this work, I was told Arista submitted a claim not a pre approval for the root canal. After speaking to my insurance, I called Arista I was told then "they were still waiting on approval", I explained the problem and was told to wait. Then i received a call, and text from Arista that I need my routine cleaning, I asked if they have any information on the pre approval for the root canal, and was told again the claim is denied. The problem, as per my insurance is Arista doesn't submit pre approvals, everything is denied by the insurance because they submit claims for process instead of pre approvals; I have paid several times for my, and my child's dental work because of Aristas negligence. After my child's root canal, my insurance confirmed that Arista has failed to submit the required back up's for pre approvals on time to do my child's root canal, I paid cash because I was told it wasn't covered, (What do you do when your child is in pain), and this is the reason they are always denied. I'm so fed up , I requested my medical records by email, I received an email with instructions, and the authorization form. The form states "48-72 hours" for the records to be provided. Waited an entire week, and there was no response to my email, or multiple calls, or voice messages. I decided to stop by Arista to follow up on the dental records, after these were printed I was told the fee of $25.00 had to be paid to release the records, (seriously this person is being paid to punch a key board during her work hours, they have so much free time on the day to text, and scroll the cellphone, didn't even get up from her chair to retrieve the black and white page, and I have to pay $25.00 because she needed to roll her eyes) when I told them that this information was not in the form emailed, or the email body instructions, I was then told they will not provide the records unless I paid. I then show them there was nothing about fees on the form, or email originally provided by Arista, I was told "if I didn't pay they will not give me the records". I then said even if I pay you, I will dispute the charge since it's not posted on the authorization form, or email instructions, the person behind the desk slap her hands in the counter and said "I'm not giving you the records unless you pay". I then asked for the manager, the same woman conveniently responded they were not in today, I then said I'll speak to Mike since the establishment bills under his name to my insurance. I patiently waited while he finished with another person, since he was listening to the entire argument about fees he mentioned that I had to pay, or they could send directly for FREE to my dentist, this option was not even mentioned earlier. I then requested the records sent to my NEW dentist, and reminded Arista about Title: Section 50-1.5 - Fees for copying records is only $0.25 per page. I recommend if choosing a dentist, or any other health professional, please read the reviews, and if you find reviews similar to the ones for Arista, then move along and find some other professional location. read more

See all

Y'all see Little Shop of Horrors? Familiarize yourself with this movie musical because Dr. Thomas is channeling Steve Martin. He had a wild and erratic bedside manner, didn't explain why he was applying topical numbing medication on a simple cleaning, tore gums to shreds, and repeatedly mocked the technicians working with him. Avoid if you can. read more

The staff is courteous and professional. I have received excellent dental care from Dr. Espinosa and DA Sandra.

They are very expensive, and they don't know what they are doing!! They hire people who don't speak English and their doctors are retired and don't know what they're doing. read more

Doctor mike, And the female doctor, I didnt get her name are very professional and kind. But That Thomas guy is a bit rude and unprofessional. Its a telling sign when none of the aids want to be in the room with him. Its sad, and it makes him more frustrated while dealing with sensitive areas such as your teeth and gums. It is pure lunacy. read more

This place has to be scam central. Useless "consultations" to stack up on people's insurances. I've seen this hasn't been this first occasion and I am positive that it won't be the last. They allegedly malpractice on their clients to keep them coming back. Unacceptable rude service. The staff is unprofessional, this is a sad excuse of a dentist office. The corona beer bottle I saw on their steps should have told it all. Stay away from this place and go somewhere professional, where they actually care about their clients health, not just the insurance bill. read more

Please listen to the reviews about this place. THEY DON'T CARE ABOUT YOUR HEALTH, ONLY CARE TO SCAM YOU FOR MORE MONEY. This was the worst customer service i've ever had in a dentist office from receptionist. Dr. Michael did a filling that Dr. Espinoza said needed to be done over because "it didn't look good". When I scheduled the appt to do it over they were telling me I had to pay for a panel. I called my insurance and they told me my panel was covered. I relayed this message and was directed to the 2nd desk in the back so the receptionist in the back can call and confirm with my insurance. The receptionist, a middle aged woman with glasses was very rude, hostile, nasty and insisted she's not going to call my insurance to double check. So I just had to leave. This was the worst customer service i've ever had in a dentist office. THEY DON'T CARE ABOUT YOUR HEALTH, ONLY ABOUT SCAMMING YOU FOR MONEY. This office doesn't deserve your money. Save yourself the stress. read more

This was by far the WORST experience I have ever had at a dental office. The office staff is incompetent and Rude. Artana has made my opinion of this office so very terrible. My claim was not submitted (although the office claimed it was) causing a delay in services. When it finally was submitted the next two times it was rejected because it was incomplete TWICE!!! SOO MUCH TIME HAD PAST BECAUSE OF THIS INCOMPETENCE, I Needed to seek treatment at a different dental office. Now it didn't end there I requested my xrays and was charged $25.00 for 6 printed pages of my xrays! Avoid this office at all costs. read more

I had a truly disappointing and frustrating experience with this dentist office. I scheduled two appointments with them, hoping to get my tooth extracted as recommended during my first visit. Unfortunately, both appointments turned out to be nothing short of a waste of my time and patience. During my first appointment, they took an X-ray of my tooth and informed me that it needed to be extracted. Fair enough. I reluctantly agreed to the extraction, and they scheduled my next appointment for two days later. On the day of my second appointment, I arrived at 8:50 am for a 9 am appointment. They called me in promptly, which initially gave me hope that they were running efficiently. However, my hopes were quickly dashed when I was left waiting in the dental chair for a whopping 40 minutes before the dentist finally decided to grace me with her presence. But wait, it gets worse! After making me wait for what felt like an eternity, the dentist nonchalantly asked me why I was there. Imagine my bewilderment when she seemed to have no recollection of my previous visit or the purpose of my second appointment - which was, mind you, to get my tooth extracted as per their recommendation. Without much ado, she casually touched the problematic tooth for no more than two seconds and then, to my utter disbelief, announced that I needed to come back to get it extracted! Are you kidding me? I had already mentally prepared myself for the extraction, and now they were sending me home with no concrete plan after making me wait and wasting my time and effort. I voiced my frustration, expressing how absurd it was to schedule an appointment explicitly for extraction only to be sent away with no progress made. In response, the receptionist started talking about "not being able to work under pressure," which made no sense to me. When she handed me my paperwork, she mentioned that I should go somewhere else for treatment. Can you believe that? They were basically kicking me out after charging my insurance twice without providing any real help whatsoever! The lack of professionalism, the wasted time, and the blatant disregard for my dental needs make this dentist office one I will never recommend. Save yourself the trouble and find a dentist who actually cares about their patients and provides meaningful dental care rather than treating you like a burden. I will gladly take my dental needs and insurance money elsewhere, and you should do the same! read more

My dad, who is 78 years old has been a patient of this horrible dentist's office for a few months. 1. The authorizations that are rejected by the insurance plans, are not being filled out properly. A general dentist named Espinosa mistreated my dad last week, March 12th. She was rude and unprofessional. She told him, he couldn't spit the water out of his mouth! When his home attendant asked why not, she told the home attendant she had to leave the room. Of course, she did, Espinos, doesn't have a witness to see her wicked behavior. My dad had a question at the end of the cleaning, Espinosa abruptly told him, "I can't answer any questions. I have another patient!" I will be notifying Dept for the Aging and HRA. It's obvious, that Espinosa has behaved this way before and no one has reported her. I've left several messages, requesting her full name and NPI. I've never received a response (email or call back)! I had to call his insurance plan. I'm sure she has family/friends give her 5 starts! Check google, the person that gave her 5 starts, has never reviewed anything. That was probably her creating that profile. This place needs to be closed down! read more

Doctors are great but they have the worst customer service system. Hara the person in charge was working while taking care of children in the park I think. it was the lowest level of customer service I have ever done. She kept repeating everything. She was not focused on the call. Call took 20 mins that should be done in just 1-3 mins. This clinic tried to fix it but it became OVER. Over called. Over text. OVER Information to the point representatives doesn't even know what they are saying. In clinic, they make you sit and check-in in this (smh) computer. Then STILL have talk to the front desk and wait in line. Simple matter. I don't see the use of front desk and all these employees for customer service. There's one sitting saying to check-in on the computer STUPIDLY JUST TO TYPE NAME AND WAIT FOR THE BLANK SCREEN DUH. I DONT REALLY SEE THE POINT! read more

Disorganized reception. Long wait for no reasons and incompetence. Had to go 2 times just see the doctor twice without actually doing anything. First time to get clearance cuz we had a heart medication and kidney dialysis. Which irrelevant. Second time cuz we had to take an antibiotic an hour before cleaning. Which we were not told or we could've taken while waiting for 2 hrs. What a scam read more

Do not go here - they schedule appointments at times when the office isn't even open, wait times are ridiculous, and everything is incredibly unprofessional. This place needs to close. read more

Dr. Espinoza is amazing! I have never ever not had any pain at the dentist! I have had so many bad dental experiences in the past that I've been afraid of going to any dentist. Dr. Espinoza examined my teeth, listened to my concerns, made a plan and then worked on my teeth so efficiently and painlessly! I wanted to hug her when I left! I'm so glad I found her! Her assistant is very nice and reassuring, too! read more

Check yourself in with zero instructions. All staff has an attitude. Waiting time over 1 hour.

So I went into this office, and immediately got taken back for X rays. Fine but I hope they are covered by insurance because they didn't really ask if I wanted them. Then I waited a full hour to get seen for the cleaning. That cleaning was TORTURE. so incredibly painful, I could see clots of blood being sucked up with the tube. I never saw an actual doctor, which is the reason I go to a dentist in the first place. The cleaning was done in 15 minutes. My teeth might be clean but i was in pure agony and I won't be going back. read more

All my Insurance claim forms for approval, were never sented or were sented incompleted, or with wrong CODES. Which in turn, ALL were DENIED, by my Insurance. Till this day 12/2023 NOTHING has been submitted, to my Insurance to correct the problem. read more

Kept changing appointment. Very unprofessional. Don't recommend. They should stop playing with patients.

Stay away from Dr.? Michael Kokolis. He placed a crown on me, which kept falling every few weeks or sometimes even days. A year passed, and he still needed to fix the problem. I went to another dentist, who told me the crown was falling because it wasn't good. It did not fit properly. And what was more, while I was there, I observed many other patients coming in for the same issue. Michael Kokolis needs to find another job. As a shoemaker, he will do much better. And do not think that because you are Greek, he will make an exception. He respects no one. read more

Don't ever visit this office. Always get a second opinion. They made me wait months to complete the treatment plan of having my cavities filled. The staff is unbelievably disorganized. No one ever picks up the phone. They take advantage of people with medicaid and submit claims for dental work I never got done. Dr. Espinosa is a kind dentist which is rare but she deserves to be in a better office. The front desk receptionist always mixes up my appts, forgets to submit my claims and never picks up the phone. Good luck speaking with a manager because anyone who runs this office is absolutely shady. Save yourself the time and money. read more

this place ghosted me after I made an appointment with them. even through the phone I could feel how rude they are... this is the worst attitude ever! read more

I saw Dr. Espinoza for a cleaning. This was the worst, most painful cleaning I have ever experienced. I was in agony. I have had many many cleanings over the years, this was simply the worst!.

Stay away. read more
