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 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 😁
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.
Have been seeing Dr Payriani for years. And he is lovely. Overall I’ve been to many tend locations. Always great service and easy to get into and schedule with. The shift lead took the time to help with a billing issue today and was very kind and thoughtful!
Best dental office experience I have ever had. HANDS DOWN. They have top of the line tech which made everything such a smooth experience, but mostly the staff goes above and beyond to be helpful and kind—from the front desk associate to the dentist all around great treatment. My dental hygienist, Kim was so attentive and you can tell he truly cares about his job. He went above and beyond to make sure my concerns were addressed even though I arrived a little late (someone give him a raise ASAP!!) Did not feel like they were pushy with any treatments that I may not need like other dentists. Truly will be a client for life.
I visited Tend Midtown on an emergency basis today and had a lot of reservations because horrible past experiences with dentists. I was blown away at how friendly and accommodating everyone was. Let me start off by saying the facility and equipment are nest level. I was greeted by Sidney who automatically made me feel better. Janelle was a Godsend. Her calming demeanor and professionalism are the reasons I will return. She completly eased my anxiety! Lisa explained everything regarding my condition and the treatment plan. This was definitely the best dental experience to date!
Tend dental is a spa for your teeth. I visited two days in a row this week and both times, the staff were welcoming, professional, and efficient. Every time I visit tend, I never have to wait, the staff is always on time. The entertainment system is so great, I have to remind myself I am in the chair for a procedure, not just to be entertained. For my 2nd visit, the email said the procedure would take 50 minutes, and that is exactly how long it took. Tend is truly the best dental office I have ever been to.
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!
Our visit was amazing. The receptionist was so kind and pleasant. The treatment we received was thorough, informative and educational. The Dental hygienist was exceptional!
Wonderful care and service. Complicated procedure yet done very well and could not have been done better. Thank you.
My first time at Tend and I’m glad I followed through with my appointment. Their office is really nice and clean and everyone was really friendly. My hygienist and Dentist were Shacore and Dr. Abernathy and they were both amazing. Shacore made me laugh the entire time and tried her best to make me feel comfortable. I would definitely go back.
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.
10/10 experience! The new Tend location in downtown Brooklyn is amazing. The location is very very clean, sparkling dare I say…but it’s the staff that made the experience so perfect. Everyone is so kind and friendly! They make you feel so comfortable! Request Ikira for your cleaning, she did a fantastic job! What an angel!
Great experience for my first visit. Everybody was super friendly, knowledgeable and efficient. Thank you for taking the stress out of going to the dentist. Both Stephanie and Tracy did a great job with my cleaning.
10/10. I was scared of everything dental before finding Tend. Amazing staff from Doctors to the Front Desk!
It's a bonus that despite the swanky feel of the office and the really thoughtful service, they don't try to upsell you and the prices for out-of-pocket expenses are reasonable and discussed upfront.
What a wonderful dental experience !! The flexibility of being able to have an early morning appointment comes in handy for people with busy schedules. My appointment started on time at 7am in a relaxing office setting. My hygienist was super thorough as was my dentist who took time to explain findings and patient to answer all my questions. What a great way to start my day. Thank you
A colleague of mine at work raved about this dental office. I was in search for a new dentist because of urgent tooth issue. Not only was able to see a doctor about my tooth the same day I inquired about the location, they are setting me up with my treatment the same week. Highly impressive practice. SUPER CLEAN AND WELCOMING. Handled my insurance and payments with decorum and ease. I highly recommend.
The best dentist office I have ever been apart of. The staff are always welcoming and helpful, the location is always clean and smells really nice and the doctors and hygienists are the most respectful, intelligent, skilled and supportive I have ever encountered. They have helped me so much physically with my smile and dental anxiety. I’m so grateful for this amazing place!
I had a fantastic experience at Tends! The entire team was professional, welcoming, and made me feel completely at ease. The hygienist did an amazing job with my cleaning—thorough yet gentle—and took the time to explain everything. The dentist was just as wonderful, addressing my concerns with care and providing clear recommendations for my dental health. The office itself is modern and inviting, making the visit even more comfortable. Highly recommend Tends for top-notch dental care!
Easy booking: everything was booked online, insurance was verified online. The ladies at the front desk welcomed me with a smile and a new Tend toothbrush/toothpaste kit bag. To top off my visit, the hygienist T. Nguyen did X-rays and the best teeth cleaning ever. I definitely recommend this place to my family. Super friendly and clean facilities
