Why people love Tend
The doctor was very informative and the staff was very nice. I was seen at my appointment time and I was in and out in less than 45 min.
From the greeting at the front desk staff to the doctor and assistants, I had a seamless experience at Tend for my root canal treatment. It was completely painless; I actually lost track of time watching a show during the treatment. Everyone made me feel at ease. Two thumbs up for Dr. Yoo, Rosa and Jonell!
My experience was wonderful. Staff and dentists are all warm, caring, and nonjudgmental. I had questions regarding billing, but they addressed it professionally and quickly, which made me feel like they genuinely care about their patients. (Their customer care along with their dentists and oral surgeons are all so professional, caring and attentive!) I need a lot of work done, and I will definitely be turning to them for extensive dental work and regular cleanings in the future. Thank you, Tend! I’m very grateful.
The staff is so friendly and professional. Everything was on time and the Invisalign process is really amazing. Such quick results.
Wasn’t looking forward to my root canal but Dr. Yu made it painless. Managed to go about my day right after the procedure. It’s been a few days since the procedure but so far so good. Also the Studio Manager, Neday was so extremely helpful. Thank you all.
First dental appointment in YEARS: Bright calming studio space. Every single person I encountered was the picture of courtesy and helpfulness- not one ounce of guilt or judgement.
When I came in, the team was so gentle with my cleaning and I never felt judged. I didnt get flossed shamed and when it came time to review my teeth, [the dentist] took the time to show me my xrays, where my cavity was (no dentist has ever done this for me) which I really appreciated.
One of my favorite parts at the end of the visit was after the dentist gave me his recos his staff showed me on the screen what my next few visits would cost me out of pocket and what my insurance would be covering. This is what visiting the dentist should be like.
I had a really nice experience at Tend - from a comprehensive scheduling process, to them running my insurance ahead of time so I knew exactly what was covered, to a great cleaning and quick dentist visit. When the dentist suggested a nightguard I was immediately told what my insurance would cover for that, so I could make my decision with all of the facts. Very happy with my experience.
They also had contactless payment, and let me know up front that there would be no cost associated with my visit based on my insurance. I’ll definitely be back! This is how all dentists should be!
I was taken in right on time, the studio was beautiful, and I loved their transparency with showing me my X-Rays and walking me through the cost of the treatments needed.
I am never leaving Tend. They make you feel comfortable, heard, and I’ve never had such a great experience at a dental office. I had 2 cavities filled and didn’t feel even feel a pinch when given the novocaine. 5 stars to the entire staff 😁
I booked my appointment online, put in my insurance info and found out how much I would have to pay for a cleaning (free!)... Then they went over my treatment plan and cost for getting my cavity filled (also free).
The best part was definitely the cleaning process, where my dental hygienist...was able to remove all the build-up on my teeth that had accumulated over a long period of time meanwhile minimizing the pain. She was so friendly and took the time to clearly explain the results of her examination...She was all-around skilled and professional and so kind.
I must say I will rate my experience from the moment I walked in to the moment I left a 10/10. The space is beautiful, you feel extremely comfortable and at ease, it is super clean, the staff is beyond nice.
I get very nervous going to the dentist but I was completely at ease here. The hygenist and dentist were extremely knowledgeable and thorough. The appointment was not rushed at all which is rare in NYC. I highly recommend Tend and can't wait to go back (who thought I'd be excited for the dentist???)!
I am being completely honest when I say I actually look forward to going to Tend. They do an extraordinary job of making sure I’m comfortable and relaxed. I just popped on a Netflix show and relaxed for a bit, and while performing the procedure they checked in on me every so often to ensure I’m still doing well...
After trying out so many dentists in NYC, I'm so glad I found Tend. [The dentist] and the rest of the staff are incredibly friendly and take their time to put you at ease.
I had the greatest experience at Tend this afternoon. I generally am quite anxious about any sort of dental experience, but from the moment I stepped foot in the office I felt welcome and at ease.
I must say this is like going to the spa. The staff is incredible from the host to the technicians to the doctors; everyone is warm, fun, smart, diligent, and professional while still creating a comfortable and enjoyable experience...I truly enjoy every visit and already am looking forward to my next cleaning (who says that?!)
I went in for a regular checkup and the whole process was a breeze. They accepted my insurance and told me their costs prior to my appointment.
The staff are so kind. The doctors take the time to talk to you and explain things clearly as well present options to you to make you feel comfortable. I don’t like the dentist’s in general and I enjoy going to TEND every time. 10/10 would recommend to everyone!
Alexa was phenomenal and made me feel comfortable, answered all my questions and was just lovely to talk to. my overall experience at tend was great and i would recommend to anyone in the area!
This was my second time visiting and both times I experienced EXCEPTIONAL service. I did not wait more than 60 seconds to be taken tot the exam room. The hygienist was amazing and gentle. The office is modern and very clean. The receptionists are always pleasant and welcoming. I will definitely be a regular. Anddddd they used my preferred name.
The staff here at Navy Yard are the best!!! Dr. Turkson, Dr. Showkatian and Roxy made me feel so comfortable once again. Im ine to be petrified of the dentist the sounds make me out of control. I use to pass out after leaving the any dental office. Since I've been coming to Tend...hasn't happened any more. There expertise in what they do made my nervousness go away. They ease my nervousness with their kind approach and gentle care. Explanations of aftercare is given as well. When you walk in door you're greeted with kindness. Thanks and ❤️ to the Navy Team!!!
I have been extremely impressed by Tend especially this location! The staff here are very friendly and take the time to explain everything and teach how to improve your oral health. You can definitely tell they care about their patients and are passionate about teeth! Will absolutely recommend to anyone for which I have already!
The hygienist was very good - thorough and attentive. Dr. Shane was also excellent - I left with a good treatment plan and clear path forward.
One of my favorite parts at the end of the visit was after the dentist gave me his recos his staff showed me on the screen what my next few visits would cost me out of pocket and what my insurance would be covering. This is what visiting the dentist should be like.
I had my wisdom teeth removed today and it was painless. The overall procedure felt quick. The staff are so polite! Thanks, everyone for making my first time a breeze.
First dental appointment in YEARS: Bright calming studio space. Every single person I encountered was the picture of courtesy and helpfulness- not one ounce of guilt or judgement.
I give my experience with tend a 10 out of 10. From walking into a beautiful inviting space and getting useful welcome gift, to staff and practitioners using your preferred name, it immediately sets you at ease. I especially loved walking into the hygienist suite where the TV monitor showed my message “Hello Manna, we’ve prepared this suite just for you.“ Each person I encountered was kind and attentive to comfort needs. They thoroughly explained each step of the process for examining my teeth then the doctor’s consultation followed by the cleaning. I am so glad that my insurance plan is in network with Tend because there isn’t another place. I’d trust with my dental health.
I had a great experience! I Came here for a cleaning/ general checkup. Doctor was very thorough and went through X-rays with me and answered all my questions. And the hygienist i had did an excellent job. He was super thoughtful and left my teeth sparkly clean without hurting me. And the office itself is adorable, it’s very clean and well decorated. Overall it was a great experience and I will be returning!
Wonderful experience at Tend Rockefeller. The staff members are friendly, the facility is super clean and modern, and my dentist Dr. Vana B is amazing. She explains the procedures very thoroughly and she is attentive. Excellent work. Dental assistant Rosa ensured I was comfortable and well-cared for throughout my appointment. I’d recommend this location.
John was very gentle and thorough with my cleaning. I felt very comfortable and my teeth were super shiny and polished after!
All of the staff at the Mosaic office were all so wonderful. They made sure I was comfortable and understand every step of the whitening process. I was their last client of the day and yet the hygienists offered me extra time to ensure I was satisfied with my results. Highly recommend Tend for any dental needs!
Wasn’t looking forward to my root canal but Dr. Yu made it painless. Managed to go about my day right after the procedure. It’s been a few days since the procedure but so far so good. Also the Studio Manager, Neday was so extremely helpful. Thank you all.
Great experience! Very friendly and professional service. I went in for a regular checkup and the whole process was a breeze. They accepted my insurance and told me their costs prior to my appointment. They were punctual and didn't make me wait in the lobby at all. You get to watch Netflix during your appointment. The office was very clean and modern as well. Best dentist experience I've ever had!
Really positive experience. Beautiful aesthetically. Every detail was thought through. Got an appointment next day. Zero wait time. The staff and drs were thorough and very kind and put me at ease even though I was very nervous! They were transparent about billing, my insurance covered the visit, no weird bills later on. I wish all doctors offices were like this.
The best part was definitely the cleaning process, where my dental hygienist...was able to remove all the build-up on my teeth that had accumulated over a long period of time meanwhile minimizing the pain. She was so friendly and took the time to clearly explain the results of her examination...She was all-around skilled and professional and so kind.
Kind, knowledgeable and thorough staff and providers. Billing was discussed with me multiple times prior to the start of my exam. I had my second visit at this location and with tend in general, and I have been quite pleased with my care and the transparency I have experienced.
